Lesson 4 Flashcards
1
Q
a place where two bones meet
A
Joint/Articulations
2
Q
immovable joints
tightly joint, no synovial joint and fluid
A
Fibrous Joint/Synarthroses
3
Q
movement occurs in fetuses and young children
A
Suture/skull type
4
Q
- connective tissue replaced by bones and they become permanently fused
- sealed joint
A
Synastosis
5
Q
- bones are close together but not touching
- held by collagenous fibers
radius, ulna
A
Syndesmoses
6
Q
- fibrous joints made up of peg and socket
root of tooth
A
Gomphoses
7
Q
- slightly movable joints
- united by a plate of hyaline cartilage or fibrocartilage disc
A
Cartilaginous joints/Amphiarthroses
8
Q
- primary cartilaginous joint
- joint composed of epiphyseal plate of hyaline cartilage that joins the diaphysis and epiphysis
- growth, not movement
A
Synchondroses
9
Q
- adult synchondroses replaced by bone
A
synostosis
10
Q
- few synchondroses are not replaced by bone
A
sternoclavicular joint
11
Q
- secondary synchondrosis
- two bony surfaces are covered by thin layer of hyaline cartilage
A
Symphyses
12
Q
- freely movable joints
- end of bones are covered with articular cartilage
- joint is lubricated by synovial joint
- enclosed by a flexible articular capsule
A
Synovial Joints/Diarthroses
13
Q
Structures of synovial joints
A
SAALT-BT
synovial cavity/joint cavity
articularly cartilage
articular capsule
ligaments
tendon
bursae
tendon sheathes
14
Q
- contains synovial membrane that secretes synovial joint
A
synovial cavity
15
Q
- covers epiphysis
- reduce friction
- end of long bones
- shock absorber
- cannot replace itself when destroyed
A
articularly cartilage
16
Q
- fibrous capsule that lines synovial cavity
- pliable -> permits movement
A
articular capsule
17
Q
- connect bone to adjacent bone
- rich supply of sensory nerves
- inelastic but permits movement
A
Ligaments
18
Q
- attached bone to bone
A
Tendon
19
Q
- flattened sacs
- cushion certain muscles
- filled with synovial fluid
A
Bursae
20
Q
- long cylindrical sacs filled with synovial fluid
- reduce friction at joint surfaces
- found in wrist, palms, fingers
A
Tendon Sheathes
21
Q
accesory ligaments
A
extracapsular and intracapsular
22
Q
articular disc
A
menisci
23
Q
Types of synovial joints
A
Hinge
Pivot
Saddle
Condyloid
Ball and socket
Gliding
(He put some candy bags and gums)
24
Q
- joint capable of extension and flexion
- elbow, knees, fingers
A
Hinge
25
- able to rotate around central axis
- C1 and C2 of head
Pivot
26
- saddle shaped
- found only between the metacarpal and carpal bones
- between trapezium and metacarpal of thumb
Saddle
27
- elongated ball and socket joint found in the atlas and occipital bone
- two direction
- between radius and scaphoid and lunate
- "knuckles"
Condyloid
28
- allows movement in many directions
- shoulder joint
Ball and socket
29
- composed of flat articular surfaces so that a bone slides to another
- joint of the wrist and ankles
Gliding
