Document Summary

Chapter 2: biological psychology (notes from lecture outline) The study of the brain, the nervous system, genetics, and how they relate to behavior and mental processes. How these unobservable physiological processes influence behavior: the nervous system: Nervous system: electrochemical communication network that connects the brain and spinal cord to all organs, muscles, and glands. Central nervous system (cns): brain and spinal cord. Peripheral nervous system (pns): nerves that radiate from the spinal cord to the rest of the body. Somatic nervous system: transmits signals from sensory organs to cns and from. Autonomic nervous system: connects cns to smooth involuntary muscles, organs, and glands: the neuron: Axon: passes messages away from the cell body to other neurons, muscles, or glands. Neural impulse: electrical signal traveling down the axon. Myelin sheath: covers the axon of some neurons and helps speed neural impulses. Terminal branches of axon: form junctions with other cells. Sensory: from tissues and sensory organs to brain and spinal cord.
