21
Q

Foramen defenition

A

round or oval opening through a bone

22
Q

Endochondral Ossification

A

replacement of cartilage with bone due to avascular properties that are outpaced by growth and leads to lack of oxygen

6 weeks to 25 y/o

23
Q

Synarthrosis Joints

A

are fibrous joints that are immovable

24
Q

Amphiarthrosis Joints

A

are cartilaginous joints that are slightly moveable

25
Diarthrosis Joints
synovial joints that are moveable
26
Synarthrosis joints types
1. skull sutures 2. syndesmoses - depends on fibre length 3. gomphoses - teeth
27
Amphiarthrosis Joints types
1. synchondroses - united by hyaline cartilage 2. symphyses - united by fibrocartilage 3. primary amphiarthroses - replaced by bone 4. secondary amphiarthroses - cartilaginous 4evr
28
Diarthroses Joint types
specialized for mobility, enclosed in a joint capsule, lined by a sereous membrane producing synovial fluid
29
Origin
does not move during contraction
30
Insertion
moves towards the origin during contrsction
31
Muscle injury location
at the myotendinous junction (MTJ)
32

nexk and throat
33
Brachial Plexus
pectoral girdle and upper limb
34
Lumbar plexus
anterior hips and thigh
35
Sacral plexus
glutes, posterior thigh, leg
36
Spinal cord ending
L1/L2
37
Dorsal root ganglion contain
sensory neurons
38
Ventral root contains
motor neurons
39
Spinal nerves contents

40
Paralysis
loss of function in a muscle or loss of a movement
41
Numbness
loss of sensation
42
Weakness/paresis
partial loss of function of muscle/movement
43
Paresthesia
partial loss of sensation
