Document Summary

Psyc 2301 the systems of the body. Nervous system, endocrine system, cardiovascular system, immune system. The nervous system: central nervous system. Consists of the brain & spinal cord: peripheral nervous system. Made up of somatic nervous system & autonomic nervous system. Connects nerve fibres to voluntary muscles & provides feedback to brain in terms of sensory info about voluntary movement. Its regulation occurs via sympathetic nervous system & parasympathetic nervous system. Sympathetic nervous system involved in stress responses (increased heart, rate, etc. : involved in mobilization of energy (catabolic) Parasympathetic nervous system: controls organs, acts antagonistically to sympathetic nervous system, pns restores body to normal after emergency has passed, pns active during digestion, for ex, involved in conversation of energy (anabolic) Hindbrain: medulla (regulation of heart rate, blood pressure, & respiration, pons (link b/w medulla & cerebellum; involved in respiration, cerebellum (coordinates voluntary muscle movement; damage results in decreased muscle tone, tremors, disturbances in posture & gait)
