Document Summary
Unit 3a: neural processing and the endocrine system. You cannot totally separate the mind from the body. Biological psychologists study the linkage and interplay between the body and the mind. Even more broadly, there is a biopsychosocial component. This concept believes we do the things we do because of (1) our bodies, (2) our minds or thinking, and (3) the culture that we live in. Sensory neurons take messages from the body, up the spinal cord, to the brain. Motor neurons take messages from the brain to the body. Interneurons are neurons within the brain that talk to one another while thinking or processing information. Cell body with a nucleus in the middle. Dendrites are feather-like fingers sticking out from the cell body. Axons are long arms that send info away from the cell body to other neurons or body parts. This insulation helps control the impulses and speeds their travel.
