Flashcards in Joints, Muscle And Blood Supply Deck (30):
1

What does arthroses mean? What are types of arthroses?

Joints
Synarthroses and diarthroses

2

What type of joints connect bones to bones via tissue? Its function

Synarthroses.
Stabilziation rather than movement

3

What are two types of synarthroses?

Fibrous joint
Cartilaginous joint

4

Where are suture joints founded? Where are Gomphosis founded?

Flat bones of skull (dense short fiber)

Short dense fiber btw tooth and tooth socket

5

What joints held together by ligament? How is it fibrous tissue compare to suture's?

Syndesmosis
Longer

6

What type of joint suture, gomphosis & syndesmosis are?

Fibrous joint

7

What joint is primary in cartilaginous joint?

Synchondrosis

8

What joint made of hyaline cartilage? Where is it?

Synchondrosis
Sternum & ribs

9

What joint made of fibrocartilage? Where is it?

Symphysis
Pubic bone

10

What joint that bone indirectly connect via the joint capsule?

Diarthroses

11

What are components of synovial joint?

Joint capsule made of fibrous tissue
Joint cavity enclosed by capsule
Synovial membrane lining capsule
Synovial fluid covering joint surface
Hyaline cartilage cover joint surfaces

12

How does hyaline cartilage get its nutrients? Why?

From joints movement. Because it doesnt have blood supply

13

What ligament and tendons do to diarthrose? Labrum? Fat pads?

Enforce joints
Raise edges
Reduce fiction

14

Where else fibrocartilaginous disks founded?

In diarthroses - joint capsule

15

How diarthroses categorized?

Based on degree of freedom

16

Uniaxial? What are those joints?

Flexion and Extension
Hinge joints
Pivot joints

17

Where do you find hinge joint?

Interphalanges and elbow joint

18

How does pivot joint work?

Rotation about an axis

19

What is biaxial? Where do you find them?

Flexion and Extension + adduction and abduction

Condyloid: metacarpal joints
Saddle

20

What is triaxial? Where you can find them?

Flex/ext + abd/add + circumduction

Ball and socket: hip and shoulder
Plane joints

21

What joint motions are there?

Spinning
Rolling
Sliding/gliding
Combined

22

When closed-packed joints happen?

When bones are the closest, joint space is smaller/ ligament and tendons are tight

23

Example o closed packed joint?

Knee extension

24

What are main factors for stabilization joints?

Shape of articulating surface
Presence of ligaments
Muscle/tendons

25

What is dynamic stability?

When muscles stabilizes joint so it can move

26

What blood come to your arm?

Subclavian arteries

27

Brachiocephalic trunk

Split into common coratid and subclavian

28

Is there subclavian trunk on the left?

No

29

Vertebral blood supply what?

B5 to part of spinal cord

30

What subclavian split into?

Brachial and axillary
