Cards (51)

  • posterior= back/ dorsal
  • anterior= front/ volar/ ventral/ bolar
  • superior= towards head
  • inferior= towards toes
  • medial= towards middle of body
  • ipsialateral is on the same side of the body
  • contralateral is opposite side of the body
  • orgin is the attschment that moves the least/ usually proximal (near the center of body)
  • insertion= more movable attachment/ usually digital
  • palpation= use of physical touch to identify structures
  • surface anatomy= you can see (palpatate/ visual skin surface)
  • boney landmarks= bone that protrudes from beneath skin
  • force = any push or pull
  • compressive force = pushing
  • tensive = pulling
  • first class levers= head/ forces on opposite sides of axis
  • second class lever= toes/ mechanical advantage/ resistive force is closer to the axis than external force
  • third class lever: the lever is at a right angle to the fulcrum, arm/ velocity
  • biomechanics= structure/ function examination
  • aponeurosis= broad fibrosis insertion that connects adjacent musclues ex. rectus sheath
  • fascia (apoerosis)= dense connective tissue
  • pimary mover (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
  • base of support= 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
