pimarymover (agonist)= produces the most force, ex. brahialis
synergist= musclues that assist the primary mover (agonist), ex. brachii
antagonist= muscules that produce the opposite movement needed to relax , ex. bicep flex ticep relax
fixators= stabillizers, ex. stability from cervical spine
force couple= muscules working together, while acting in diffrent directions to stabalize a joint
joint = a articulation between two muscules
singe/multiple muscules act on all joints they come across
baseofsupport= how stable you are/ staggared + wide= more stability/ parallel + closed = less stable
compression of the brachial plexus leads to TOS (thoracic outlet syndrome)
bones= dense, porous, calcified conective tissue
muscules= tissue capable of contrating to cause body movement
tendons= connect muscle to bone
ligiments= connect bone to bone
superfical fascia= forms thin connective sheet immediately deep to skin (ex. thoracolumbar fascia on back)
deep fascia = surrounds fucntional groups of muscules holding them together in muscular compartments (ex. lower leg is divided into four fascia compartments)
retinaculum= strap tendons in a particuar location or position (ex. flexor retinaculum of anterior wrist)
bursa = small fluid filled sack that reduces friction between two structures
cartilage = tough elastic, fibrous connective tissue found in various parts of the body such as joints, outer ear, and larynx
fibrocartilage = numerous thick bundles of collogen fibers (ex. structure in the skull and intervertebral discs
