Chapter 8 - Types of Synovial Joints

Question 1

What are the six major types of synovial joints?

Answer 1

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

Question 2

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

Answer 2

A ball-and-socket joint (spheroidal joint)

Question 3

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

Answer 3

Condylar joint (ellipsoidal joint)

Question 4

Rotational movement is not possible in this type of joint

Answer 4

Condylar joint (ellipsoidal joint)

Question 5

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

Answer 5

Plane joints (gliding joints)

Question 6

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

Answer 6

Plane joints (gliding joints)

Question 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

Answer 7

Plane joints (gliding joints)

Question 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

Answer 8

Hinge joints

Question 9

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

Answer 9

Pivot joint (trochoid joint)

Question 10

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

Answer 10

Pivot joint (trochoid joint)

Question 11

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

Answer 11

Saddle joint (sellar joint)

Question 12

Concave means

Answer 12

Curving in or hollowed inward

Question 13

Convex means

Answer 13

Curving out or bulging outward
