Somatic nervous system (external environment: carry sensory information to brain (vision, hearing, skin, joints, carry motor info from brain to control voluntary movements (muscles, neurotransmitter is acetylcholine, at neuromuscular junctions. Glucose concentrations, other physical and chemical factors: central nervous system. Consists of the brain and the spinal cord. Functions: integration of information, learning and memory, coordination of activity. Cerebral cortex outmost layer, process sensory info, control muscles, association area, reasoning and language, when awake cerebral cortex is active, less active when sleeping or under influence of sedating drugs. Basal ganglia maintenance of proper muscle tone (keep legs straight when you are relaxing) Hypothalamus near base on brain, above pituitary gland, involved with feeding, drinking, temperature regulation and sexual behaviour; involved with hormonal output. Limbic system emotion, memory, physical activity has amygdala, nucleus accumbens and hippocampus also involved with sexual/eating/natural rewards behaviour.
