neurons
nervecell
–cell body
–axons
–dendrites
myelin –white mater
non myelinated–grey matter
dendrates
recieves impulses to cell body
axons
send signal
afferant nerves
sensory nerves
efferent nerves
motor nerves
conduct from spinal cord to perefery
spinal cord
through vertibral foreman in each indevidual vertebre
posterior horn
transmits sensory impulses
afferent
anterior horn
transmits motor impulses
efferent
motor impulses travel
from brain down spinal cord through anterior horn and out of the periphery via peripheral nerves
sensory impulses travel

from periphery via peripheral nerves to anterior horn brain down spinal cord through and out of the

dermatome
area of skin supplied with sensory part of a spinal nerve
myotome
a muscle (or group of muscles) innervated by a single spinal segment
cervical plexus
c1–c4 innervates neck muscles
brachial plexus
C5–T1
innervates upper extremity muscles
lumbosacral plexus
L1–S5
innervates lower extremity muscles
shoulder girdle
clavicle and scapula
shoulder complex
shoulder girdle and glenohumoral joint
scapula
clavivle
sternum
humurous
ribcage
scapulothoracic joint
allows scapula to move against ribcage but no articular surface
(no fixed point of rotation)
not conventional joint
scapula
triangular shaped bone on from t2–7
spine of scapula t3–4
sternum
flat bone anterior chest
manubrium
body
xiphoid process
clavicle
collar bone
sternal end
acromium end
body
scapula medial (vertebral) border
side closest to spine
scapula axilary border
side closest to the arm
scapula spine
posterior ridge
coracoid process of scapula
anterior scapula process
acromium process of scapula
posterior scapula process
sternalclavicular SC joint
medial aspect of the clavicle with the sternum
only attachment
elevation depression
protraction retraction
axial rotation of the clavical
Acromioclavicular joint AC joint
articulationof the acromium process of the scapula with the lateral end of the clavicle
allows scapular movement in all three planes
up downward rotation
horizontal
scapulathoracic joint movement
elevation depression
proraction retraction
upward and downward rotation
scapular tilt superior end of the scapular hyperextends
companion motions Glenohumaral joint
movement of the glenohumaral joint there is also movement in the scapulothoracic joint
scapulohumoral rhythm

1st 30 degeres gleno humoral
after that the relationship is 2–1 glenohumaral
to scapular
