1

What are the six major types of synovial joints?

Ball-and-socket joints, condylar joints, plane joints, hinge joints, pivot joints, and saddle joints

2

Consists of a bone with a globular shaped head that articulates with the cup-shaped cavity of another bone

A ball-and-socket joint (spheroidal joint)

3

The ovoid condyle of one bone fits into the elliptical cavity of another bone, as in the joints between the metacarpals and phalanges

Condylar joint (ellipsoidal joint)

4

Rotational movement is not possible in this type of joint

Condylar joint (ellipsoidal joint)

5

The articulating surfaces of these joints are nearly flat or slightly curved

Plane joints (gliding joints)

6

These joints allow sliding or back-and-forth motion and twisting movement

Plane joints (gliding joints)

7

Most of the joints in the wrist and ankle, as well as those between the articular processes of vertebrae, belong in this category of joints

Plane joints (gliding joints)

8

In this joint, the convex surface of one bone fits into the concave surface of another, as in the elbow and the joints of the phalanges

Hinge joints

9

In this joint, the cylindrical surface of one bone rotates in a ring formed of bone and ligament

Pivot joint (trochoid joint)

10

This type of joint functions in the neck as the head turns from side to side

Pivot joint (trochoid joint)

11

This type of joint forms between bones whose articulating surfaces have both concave and convex regions

Saddle joint (sellar joint)

12

Concave means

Curving in or hollowed inward

13

Convex means

Curving out or bulging outward
