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.
