Is the metacarpophalangeal joint a saddle joint?

The first CMC joint is a saddle-shaped very mobile articulation between the trapezium and the base of the first metacarpal. It allows 40° to 50° of thumb flexion–extension parallel to the plane of the palm and 40° to 70° of adduction–abduction perpendicular to the plane of the palm.

What are the 6 types of synovial joint?

Synovial joints are often further classified by the type of movements they permit. There are six such classifications: hinge (elbow) saddle (carpometacarpal joint) planar (acromioclavicular joint) pivot (atlantoaxial joint) condyloid (metacarpophalangeal joint) and ball and socket (hip joint).

How many types of joints are there in the human body?

A joint is the part of the body where two or more bones meet to allow movement. Generally speaking the greater the range of movement the higher the risk of injury because the strength of the joint is reduced. The six types of freely movable joint include ball and socket saddle hinge condyloid pivot and gliding.

Where are hinge joints found?

What are the 14 phalanges?

A phalange is any of the bones in the fingers and toes. In humans there are 14 phalanges in each hand and foot 2 in each thumb and big toe and 3 in the remaining digits. They are connected to the metacarpals in the hand and the metatarsals in the foot.

A condyloid joint is a modified ball and socket joint that allows for flexion extension abduction and adduction movements.

Are tendons?

A tendon is a cord of strong flexible tissue similar to a rope. Tendons connect your muscles to your bones. Tendons let us move our limbs. They also help prevent muscle injury by absorbing some of the impact your muscles take when you run jump or do other movements.

What are the characteristics of a saddle joint?
