_____ 1. The greatest range of mobility of any joint in the body is found in the
- a. knee joint.
- b. hip joint.
- c. glenohumeral joint.
- d. elbow joint.
Introduction:
Joints are defined as the strong connections that join bones, teeth and cartilage of the body to one another. Each joint which is present in different parts of body is specialized in its shape and structural components to control the range of motion.
Answer to Problem 1DYKB
Correct answer:
The greatest range of mobility of any joint in a body is found in glenohumeral joint. Therefore, option c. is correct.
Explanation of Solution
Reason for the correct statement:
Option c. is given as “glenohumeral joint”. The shoulder joint is also called glenohumeral joint. It is a type of ball-and-socket joint which is formed by the articulation between head of humerus and glenoid cavity of the scapula. It supports the extent range of motion in any joint of body but is unstable due to frequent dislocation.
Hence, option c. is correct.
Reasons for the incorrect statements:
Option a. is given as “knee joint”. It is the largest and most complex joint of body. It is capable of providing lateral gliding and slight rotation. Hence, option a. is incorrect
Option b. is given as “hip joint”. It is a type of joint formed between the head of the femur and concave acetabulum of the os coxae. It is less mobile and more stable as it supports the body weight. Hence, option b. is incorrect.
Option d. is given as “elbow joint”. Elbow joint is a hinge joint which facilitates the movement of hands. Hence, option d. is incorrect.
Hence, options a., b., and d. are incorrect.
The glenohumeral joint is shoulder joint which is most flexible and unstable joint of body.
