Flashcards in Exam 1 Part four Deck (25):
1

Joint between sternum and clavicle

Sternoclavicular joint

2

Joint between tooth and jaw

Gomphosis

3

Bursa

Sac filled with synovial fluid

4

Palm fases posteriorly

Pronation

5

Standing on tiptoe

Plantar flexion

6

Intervertebral disc has

anulus fibrosus and nucleus pulposus

7

Articulation among tibia, fibula, & talus

Talocrual joint

8

Menisci is located

in knee joint

9

The greatest range of mobility of any joint in the body is found in the?

Glenohumeral joint

10

The movement of the foot that turns the sole laterally is called

Eversion

11

A_____ is formed when two bones previously connected in a suture fuse

Synostosis

12

The ligament that helps to maintain the alignment of the condyles between the femur & the tibia and to limit the anterior movement of the tibia on the femur is the

Anterior cruciate ligament

13

The glenohumeral joint is primarily stabilized b the

Rotator cuff muscles that move the humerus

14

In a biaxial articulation

Movement can occur in two planes

15

A metacarpophalangeal (MP) joint, which has oval articulating surfaces and permits movement in two planes, is what type of synovial joint?

Condylar

16

What is a function of synovial fluid?

*Lubricates the joint
*Provides nutrients for articular cartilage
*Absorbs shock within the joint

17

What is the differences between fibrous joints and cartilaginous joints and synovial joints

Fibrous joints- occur where bones are held together by dense regular (fibrous) connective tissue
Cartilaginous joints- occurs where bones are joined by cartilage
Synovial joints-Has fluid-filled joint cavity that separates the cartilage-covered articulating surfaces of the bones. The articulating surfaces are enclosed within a capsule, & the bones are also joined by various ligaments

18

Describe all joints that are functionally classified as synarthroses

*Tooth to jaw
*Lambdoid suture (connects occipital & parietal bones)
*Epiphyseal plates in growing bones; costochondral joints

19

Describe the basic anatomy of the glenohumeral joint

Ball and socket joint formed by the articulation of the head of the humerus and the glenoid cavity of the scapula.
*Permits greatest range of motion of any joint in the body

20

Synarthrosis is

An immobile joint

21

Amphiarthrosis is

A slightly mobile joint

22

Diarthrosis is

A freely mobile joint

23

A gomphosis is

Resembles a peg in socket. The only ones in the human body are the articulations of the roots of individual teeth with the sockets of the mandible and the maxillae

24

Anatomy of synovial joints

Freely mobile atriculations. Bones in this joint are separated by a space called a joint cavity.
These joints have several basic features:
*An articular capsule
*joint cavity
*synovial fluid
*articular cartilage
*ligaments
*nerves and blood vessels

25

All synovial joints are classified as

Diarthroses
