Question 2
Name the type of joint between the following:-
(a) atlas/axis
(b) carpal/metacarpal of thumb
(c) between phalanges
(d) femur/acetabulum
(e) between cranial bones
(f) between pubic bones in the pelvic girdle
ANS The types of joints between the specified bones are as follows:
(a) Atlas/Axis: This is a pivot joint, allowing for rotation of the head.
(b) Carpal/Metacarpal of Thumb: This is a saddle joint, which allows for a wide range of movements, including opposition of the thumb.
(c) Between Phalanges: These are hinge joints, allowing for flexion and extension movements.
(d) Femur/Acetabulum (Hip Joint): This is a ball-and-socket joint, which permits multidirectional movement and rotation.
(e) Between Cranial Bones: These are fibrous joints, specifically sutures, which are immovable.
(f) Between Pubic Bones in the Pelvic Girdle: This is a cartilaginous joint, specifically a symphysis, which allows for limited movement and provides a cushioning effect.
