Document Summary
Dualism- the mind and body are separate entities, but they interact. Pineal gland- site in the brain where the mind and body interact; seat of thought of the soul. Somatic nervous system converts instructions from central nervous system to skeletal muscles. Autonomic nervous system- regulates organs & involuntary bodily functions. Sympathetic nervous system- controls body"s response to perceived threats; fight or flight response. Parasympathetic nervous system- controls homeostasis & the body at rest; Rest & digest function; facilitates vegetative, nonemergency responses. Cerebral cortex: largely responsible for higher brain functions, including sensation, voluntary muscle movement, thought, reasoning, and memory. Cerebellum: responsible for fine motor control and balance. Glial cells: surround neurons and provide support for and insulation between them; most abundant. 3 major types of neurons: motor neurons: convey messages to skeletal motor fibers in the muscles, sensory neurons: convey info from sensory organs, interneurons: convey info from one neuron to the next.
