• Spindles: Receptors sensitive to change in length of the muscle and rate of that change (Cause muscle to contract when excited)
• GTO: Receptors sensitive to change in tension of the muscle and the rate of that change. (Cause musc to relax when excited)

Flattened or indented portion of bone, which can be a muscle of attachment site

Projection protruding from bone where muscles, tendons, and ligaments can attach

Joint motion

Held together by a joint capsule and ligaments and are most associated with movement in body (80% of joints in body) Include condyoid, hinge, saddle, pivot, ball and socket.

Joints that do not have a joint cavity connective tissue or cartilage (sutures of skull)

All linked together, movement of one directly affects the motion of others.

Primary connective tissue that connects bones together and provides stability, input to the nervous system, guidance, and the limitation of improper joint mvmnt

Poor vascularity, very slow repair

The functional unit of muscle that produces muscular contraction and consists of repeating sections of actin and myosin

The contraction of a muscle generated by neural stimulation

A motor neuron and all of the muscle fibers it innervates

Chemical messengers that cross synapes to transmit electrical impulses from the nerve of the muscle

Slow twitch, less force produced, slow to fatigue, long term contractions (Stabilization)

Fast Twitch, dec oxygen delivery, more force, quick to fatigue, short term contractions

Prime mover. Chest press-Pectoralis Major

Assist prime mover. Chest press-Anterior delt, triceps

Stabilize while prime mover and synergist work. Chest press-Rotator cuff

Oppose prime mover. Chest press(posterior delt)
