Question 1

What is a joint (articulation)?

Answer 1

a point which 2 bones interact

Question 2

What are the 3 functions of joints?

Answer 2

1. help facilitate body movement by directing the movement of bone
2. Stabilize the position of bones relative to one another
3. to provide a bit of flexibility to the skeleton

Question 3

What are the classification of joints?

Answer 3

functional classification & structural classification

Question 4

What are the 3 types of functional classification of joints?

Answer 4

Synarthroses, Amphiarthroses, Diarthroses

Question 5

What is synarthroses? what are 3 examples?

Answer 5

its an immovable joints: suture joints in your skull, gomphoses, Syndesmoses

Question 6

What is Amphiathroses? What is an example?

Answer 6

Slightly moveable joints: intervertebral joints

Question 7

what is diarthroses?

Answer 7

freely moveable joints

Question 8

What are the types of structural classification?

Answer 8

fibrous, cartilaginous, synovial

Question 9

what are 3 examples of synarthrosis?

Answer 9

suture joints in your skull, gomphoses, Syndesmoses

Question 10

What is an example of Amphiarthroses?

Answer 10

intervertebral joints

Question 11

are synovial joints freely moveable?

Answer 11

True

Question 12

the 3 type of fibrous joints?

Answer 12

Suture, Syndesmosis, gomphosis

Question 13

Are all fibrous joints characterized as synarthrosis?

Answer 13

True they are functionally immovable joints

Question 14

Where are sutures located?

Answer 14

in the skull between cranial bones & facial bones

Question 15

What are examples of syndesmosis?

Answer 15

femoral tibial joint

Question 16

are gomphosis strong connection between teeth & skull

Answer 16

true they are immoveable(synovial)

Question 17

what are cartilaginous joints?

Answer 17

bones held together by cartilage (hyaline cartilage/fibrocartilage)

Question 18

Examples of cartilaginous joints

Answer 18

synchondrosis: bones joined by hyaline cartilage

Symphysis: 2 fibrocartilage CT attached one bone to another

Question 19

What characteristics do all synovial joints share?

Answer 19

1. Diarthrosis
   2.Stabilized by a ligament externally
2. joint cavity

Question 20

ID #1.describe & identify the function.

Answer 20

Ligament, made of dense regular CT stabilizes all synovial joints externally

Question 21

ID #4. describe & identify the function.

Answer 21

Synovial capsule(fibrous capsule):
contains dense irregular connective tissue called ligaments: provides strength & flexibility to the joint

Question 22

ID #5 describe & identify the function.

Answer 22

Synovial membrane: areolar CT covers all internal joint surface

secreates synovial fluid into the cavity

Question 23

ID #2. describe & identify the function.

Answer 23

joint cavity: contains small amount of synovial fluid but expands when fluid accumulates

Question 24

the function of synovial fluid?

Answer 24

Provides lubrication to reduce friction between the bones of the joint; nourishes cells of the cartilages

Question 25

what is a bursa?

Answer 25

Are fluid – filled sacs prevent friction between skin, muscle, or tendons and an underlying bone

Question 26

What is a meniscus?

Answer 26

shock absorbers and stabilize the knee
