vertebral notches
- = indentation at the edge of the bone
- a. intervertebral foramen
- function: transmits spinal nerves and radicular vessels
-

Function of skeletal muscle
- stabilize or move bones at joints
- generate body heat
-
Name the types of muscle attachments and describe them.
- 1. origin: proximal and stationary during the movement
- 2. insertion: distal and moves
- 3. tendons: attaches muscle to bone
- 4. aponeurosis: broad sheet-like tendon
-
What are the functional groups of skeletal muscle?
- 1. synergists: muscles that act together ex. brachialis and biceps brachii
- 2. antagonists: an action that opposes a different muscle group ex. triceps is an antagonist to the biceps brachii
-
nomenclature of skeletal muscles are made from...
- 1. function
- 2. attachment
- 3. appearance
-
what is the fascicular arrangment of muscle fiber?
- perimysium: bundle of muscle fibers
- epimysium: surrounds entire muscle
- endomysium: surrouns muscle fibers
