| A | B |
|---|
| Efferent | Take impulses from the spinal cord to the muscles to produce movement |
| Afferent | Take impulses from the six senses to the cord so that we may monitor temperature, pain, joint position, visual orientation, etc. in order to respond to the environment and/or to correct movements |
| Central Nervous System | Brain and Spinal Cord |
| Peripheral Nervous System | Autonomic and Somatic Nervous System |
| Autonomic Nervous System | Parasympathetic and Sympathetic |
| Frontal lobe | General intellect and motor control |
| Temporal lobe | audition |
| Parietal lobe | general sensation |
| Occipital lobe | vision |
| Thalamus | acts as a sensory integration center-a "sensation switchboard". |
| Hypothalmus | acts to regulate metabolic rate and body temperature. |
| Cerebellum | plays an integral role in controlling rapid and complex movements. |
| Brain stem | midbrain, pons, and medulla oblongata |
| Sympathetic Nervous System | evokes a "Fight or Flight" response when stressed (pupils dilate, salivation decreases, perspiration increases, etc.. |
| Parasympathetic | Basically, the exact opposite of the sympathetic response. |
| Hypertrophy | due to build up of proteins within the fiber and is directly related to volume of training if minimal intensity has been reached |
| Muscle Spindles | found in parallel with the skeletal muscle fibers/extrafusal fibers (actually in the muscle in between the skeletal muscle fibers) |
| Golgi tendon Organ | monitors stretch in the tendon-acts as strain gauges and prevents damage during excessive force generation |
| Proprioceptor | receptors that provide the CNS with information about body position |
| Acute Muscle Soreness | Manifests at the end of a tough set or workout-caused by lactic acid and edema. |
| Neurons (3 parts) | cell body, dendrites, and axon |
| Vestibular apparatus | is an organ located in the inner ear and is responsible for maintaining general equilibrium |
| Parkinson's Disease | a disorder of the basal ganglia resulting in increased involuntary movement of tremors. |
| Kinesthesia | refers to conscious recognition of the position of body parts with respect to each other |
| Synapse | contact between the axon of one neuron and the dendrite of another neuron |
| Reflex arc | is the nerve pathway from the receptor to CNS and from the CNS along a motor pathway back to the efferent organ |
| All-or-None Law | If a nerve impulse is initiated, the impulse will travel the entire length of the axon w/o a decrease in voltage. |
