commonalities: originate from axial skeleton (broad answer)

Insert on medial border of scapula

Metacarpals only articulate with what row of the carpals

distal row

trapizeus origin insertion action innervation

origin: occiptal bone

Insertion:lateral clavicle ,spine, and acromion process of scapula

action:

-superior fibers: elevate scapula

-middle fibers: retract scapula

-inferior fibers: depress scapula

innervation: spinal accesory nerve (CNX)

Serrtatus group includes which muscles?

1.serratus anterior

2.rhombodieus

serrtatus anterior origin insertion action innervation

origin: outer surface of ribs

insertion: medial border of scapula

action:protract, retract scapula

innervation:brachial plexis

Rhomboideus origin insertion action innervation

origin: spinous process of vertebrae C7-T5

insertion: medial border of scapula (dorsal to seratus anterior)

action: elevate and retract scapula

innervation: brachial plexus

levator scapule

origin: transverse process of vertebrae C1-C7

insertion: medial border of scapula (superior to rhomboideus)

action: elevate scapula

innervation: brachial plexus

The brachial plexus emerges from which spinal nerves

C5, C6, C7, C8, C8, T1

what does the brachial plexis consist of

roots, trunks, divisions, cords, nerves

ventral rami=____ plexis roots

brachial plexis roots

brachial plexis has how many nerves that arise from medial and lateral cords what are they

3 nerves

1. musculocutaneous n(lateral)

2. median n (medial +lateral)

3. ulnar n (medial)

brachail plexis has how many nerves that arise from the posterior cord what are they

2 nerves

1. axillary n (branches out laterally)

2. radial n

what is disc prolapse, what can it do in the neck

hernaited disc

it can press on one of the spinal roots (C5-T1)

-this causes pain, numbness, weakness

if one root is compressed the nerves that derive from it are affected
