Question

what is the difference between pivotal joint and ball socket​

Answer 1

Ball and socket joint- In this joint the rounded end of one bone fits into the cavity (hollow space) of another bone.This type of bone allows movement in all directions.

Eg: Shoulder joint ans hip joint.We can rotate our arms and legs due to the ball and socket joint.

Pivotal joint-Such joints allow only rotation.The joint where our neck joins the head is a pivotal joint.It allows the head to move backward and forward and to our left and right.The head rotates over a cylindrical bone of the neck.

Answer 2

Answer:

The fundamental difference is that a ball and socket joint, such as the shoulder, may move in practically all directions, but a pivot joint is monoaxial, meaning it can only rotate in one axis, such as the elbow.

Explanation:

Pivot Joint

• This form of the joint commonly known as the trochoid joint.
• A cylinder-shaped bone rotates within another ligament that forms a ring around the joint in this joint.
• These are uniaxial joints that can rotate.
• There is just one degree of freedom.
• Examples of pivot joints are the pivot joints in the neck, which allow the head to rotate, and the pivot joints between the radius and ulna, which aid in forearm rotation.

ball-and-socket joint (also known as spheroidal joint)

• Its joint in which one bone's rounded surface glides within a depression on another bone,

• There are three degrees of freedom.
• These joints have the greatest range of mobility and the greatest diversity of directions of any synovial joint.
• Ball and socket joints are classified into two types: condyloidal and enarthrodial --- Biaxial ball and socket joints are other names for condyloidal joints. Multiaxial ball and socket joints are other names for enarthrodial joints.

• Shoulder and hip joints are two examples.
