The diverse body skeletal structures
Even though humans can be traced to a common origin by religion and historical basis, biology has been relied on to point on the diverse body composition that makes people assume individual uniqueness. Biology has provided disciplines where people can understand their bodies; however, complex it may look or be perceived. While anatomy offers a platform for understanding the structure of the human body, physiology enables students to discover the various functionality that is played by different organs for the general good of the overall body (Tortora and Derrickson 2). Moreover, students are never limited to what they can learn about the human body. Thus, they can delve into the motion of various body parts through the discipline of Kinesiology. This paper explains the reasons for the range of motion limitations and unique skeletal differences between students.
While everyone has an endowment of a normal range of motion, people possess diverse abilities required to achieve and maintain the normal level. Soucie et al. (502) define a limited range of motion as a condition when the body joints register reduced movement ability. The limited range of movement can be attributed to a series of factors, some of which are biological and beyond the control of human activities and often undertaken for body well-being and health. While some factors lead to an increased range of motion, some promote a low range of motion within a population.
Injury of the body has a significant impact on the range of motion. When a body is injured, there is interference in the muscles (Greene and Susan 6). A person who has previously been engaged in an injury will have scared tissue due to the previous experience; hence they fail to support the joints and overall body movements as required for the normal range. Therefore, the muscles lose their ability to contract and relax, which is necessary for effective movements within the body. Notably, students with a specific medical condition will exhibit a restricted and limited range of motion. For instance, students with spinal injuries and compromised immune systems that extend their effects to the body joints have a low range of motion. Besides, the students with bacterial infection within the body joints will have a limited range of motion since it negatively affects the joints and hinders their normal functions.
Physical injuries of the body can interfere with the joints hence leads to a limited range of motion (Greene and Susan 11). For instance, a dislocation of the joint through injuries leads to non-function joints that cannot support the body’s normal movement. Fractures in the body, such as at the elbow, also contribute to the limited range of motion. Therefore, students who have past injuries that have affected diverse body parts and joints are likely to have a limited range of motion.
The different structure of joints contributes to the variation in the range of motion. The biological makeup of muscles, bones, and cartilage often varies from one person to another (Soucie et al. 505). Thus, one student will have a specific structure that is different from another student within the same population or learning institution. While either tissues or cartilages join bones, their composition also differs from one person to another. Additionally, internal resistance within the body joint may also contribute to the limited range of motion. People with higher internal resistance within their joints are prone to a limited range of motion. Therefore, the structure of the bones determines the speed of movement of the joints. While some students may prefer bony structures, they may lead to a significant hindrance to the movement of the joints. The composition of the body and joint structure may favor or inhibit range of motion, making students have variation in the range of motion.
Nutrition is essential for establishing a healthy body, impacting the development, and consequently affecting its movement and general functioning (Tortora and Derrickson 10). An adequate supply of nutrients contributes to the formation and development of the bones. For instance, the consumption of nutrients, such as calcium and potassium is essential for bone development. Students with poor nutrition will have impaired bone structure, while proper nutrition promotes effective bone development needed for movements of the joints. Nutrients are also required for the tissues and muscle development needed for a high range of motion.
Age difference impacts not only the biological formation, function, and structure of the body (Arshad 2). Learning institution allows students of different ages to enroll in their studies. According to Arshad (4), age contributes significantly to the variations in the range of motion of the body parts. While the aged students may register a decrease in the range of motion, younger students are likely to record a high range of motion in the joints. Besides, the old students who are above forty years experience a decline in muscle properties. Consequently, the strength of the muscles among aging students reduced, which leads to a low range of motion. Young students remain active in movements and performing various activities within learning institutions, while the old students are often passive in activities that involved the movement of the body. Consequently, the young learner registers a high range of motion within their bodies than older students.
Gender also contributes to the skeletal variation and the limitation in the range of motion. While the general human population is believed to have a normal range of motion in the body parts such as the hips, research studies have assisted in revealing variation in the range of motion at the hips among the male and female. According to Czuppon et al. (665), the males have a reduced range of motion in their hips while females have high ROM. The difference in sex can affect the specific body joints that are essential in contributing to the body motions. Notably, the anatomic differences between the male and the females lead to variations in their range of motion (Czuppon et al. 667). The body structure for the males is different from those of the women. Anatomic composition of the women allows them to support motion within their body joints. On the other hand, the structure and composition of males limit the joints’ movements, including the hips. Therefore, a significant decline in the range of motion is recorded.
While the male students will register a low range of motion, their female counterparts will register a high range of motion.
Notably, the female skeleton and the male skeleton have diverse features attributed to their different gender sets. The females have skeletons that are smoother than those of the males (Arshad 16). Besides, the female skeleton tends to be much delicate than the male skeleton. While the rig cage among the females is small and round, those of the male counterpart is often extensive. Further, the structure of the female lumbar curve is distinct and different from those of the males. They are greater and assumes a stretched length than those of the men. The variation in the skeleton structure unique skeletal differences between students.
Undeniably, students within a learning institution often come from diverse races and ethnic backgrounds. At the same time, some may be white, while others are black. There is a significant skeletal difference between white students and black students. According to Pollitzer and Anderson (1250), the bone mass among black students is higher than that of white students, leading to skeletal differences. Besides, the material density in the born of black students tends to be higher than white students. A comparison between the black and white men of the same age reveals that the blacks possess limbs that are longer than the whites. Thus, there are differences in skeletal characteristics that are experienced due to the ethnic variation of students in a given learning institution.
Exercise is a determinant of the level of the range of motion in a given population. According to Greene and Susan (25), people who engage much in exercise activities would not experience a limited range of motion compared to those who do not take part in any active exercise. Regular exercise assists the body muscles to remain active and support movement within the joints. Besides, practice eliminates instances of stiffness and lowers swelling within the body joints and muscles, which may lead to a limited range of motion (Greene and Susan 27). Thus, students who engage in different excise activities will posses’ high range of motion. In contrast, those who never engage in exercises shall register a low range of motion and subsequently limited range of motion.
Range of motion is impacted through different types of joints movement that people experience within the body (Soucie et al. 507) Depending on the movement that is often experienced, one may assume a low or high range of motion. For instance, some people expose their joint into the extension movement. The extension leads to significant movements, the muscle contraction is experienced, and the process leads to a straightening of the joint, promoting a high range of motion. Moreover, the flexion joint movement leads to the bending of the joints. For instance, through the bending of the elbow, one can decrease the angle between the joint, thus promoting motion. Through abduction and adduction, the joints are allowed either to move away or towards the central axis. The central axis acts as the fulcrum for body movements. Students much engaged in the extension, flexion, and abduction of the joins are less prone to a limited range of motion than those who never allow their body joint to experience such movements.
In conclusion, people experience a range of motion limitations and unique skeletal differences due to various factors. The diverse body skeletal structures, exercise, and types of joint movements are responsible for the differences. Age variation and kind of sex also contributes to the skeletal differences and range of motion limitation. The structure of the joints, previous injuries lead to a limited range of motion. Even though the range of motion limitations are undesirable among students, they are caused by factors that are beyond human control.
