JOINTS AND CONNECTIVE TISSUE

Question 1

What is connective tissue and what does it provide?

Answer 1

Is a classification of tissue that all share a common molecular composition. It provides support, protection, and give structure to other tissues in body.

Question 2

Examples of connective tissue in the body

Answer 2

Bones, cartiliage, tendons, joint capsules, fascia, blood and blood vessels

Question 3

What is flexion

Answer 3

Decrease angle between body parts on either side of join

Question 4

T or F: Skeletal muscle is connective tissue?

Answer 4

False

Question 5

What is extension

Answer 5

Increase angle between body parts on either side of joint

Question 6

what is abduction

Answer 6

movement away from midline

Question 7

what is adduction

Answer 7

movement towards midline

Question 8

what is medial rotation/internal rotation

Answer 8

Rotational moves towards midline

Question 9

what is lateral/ external rotation

Answer 9

rotational movement away from midline

Question 10

define elevation

Answer 10

move superiorly

Question 11

define depression

Answer 11

move inferiorly

Question 12

What are solid joints

Answer 12

No joint cavity present. Connected by stiff tissue. Little to no movement

Question 13

what is synovial joints

Answer 13

have small cavities, which is surrounded by a joint capsule. Small cavity filled with synovial fluid which allows for movement

Question 14

how many synovial joints are there?

Answer 14

seven

Question 15

Plane joints:
Shape:
What motion:
Example:

Answer 15

flat or slightly convex/concave
sliding/gliding motion
AC joint (acromioclavicular joint)

Question 16

convex definition

Answer 16

having an outline or surface curved like exterior of sphere

Question 17

concave definition

Answer 17

having an outline ore surface that curves inward like interior of circle

Question 18

Hinge Joint:
shape:
Plane:
Example:

Answer 18

surfaces are convex or concave
permits flexion/extension
humero-ulnar joint

Question 19

pivot joint:
shape:
Plane:
Example:

Answer 19

one cylindrical bone rotates within concavity of other bone. permita rotation.
atlanto-axial joint

Question 20

what is condyle

Answer 20

rounded bump at end of bones which forms articulation with other bone

Question 21

bicondylar joint
shape
planes
what does it permit
examples

Answer 21

when 2 slightly convex bone surfaces fit into 2 slightly concave surfaces. When 2 condyles are present, rotation can occur. Allows movement in 2 planes. 1 full movement, other limited.Knee joint flexion extension/ rotation

Question 22

condylar
AKA
shape
planes
what does it permit
examples

Answer 22

ellipsoid joint
when 1 slightly convex bone surface fits into slightly concave surface
does not allow for rotation when only one condyle is present
allows movement in 2 planes that are right angles to eachother.
TMJ

Question 23

Saddle joint
shape
planes
what does it permit
examples

Answer 23

surfaces are saddle shape
allows movement in 2 planes
sternoclavicular joint (SC)
permits flexion, extension, adbuction, adduction

Question 24

Ball and socket
shape
planes
what does it permit
examples

Answer 24

The rounded bone surface (ball) fits into socket of another bone surface. Allows movement in multiple planes
Hip joint
Flexion/extension, rotation, abduction/adduction

Question 25

What is plantar flexion

Answer 25

Flex towards the plantar surface

Question 26

What is dorsifelxion

Answer 26

Flex towards dorsal surface
