AP Psych: Unit 1.3- Overview of the Nervous System (Notes Version)

Neurons

Specialized cell that serves as the building block of the nervous system, transmitting electrical and chemical signals throughout the body

Glial Cells

The support cells of the nervous system, provide structural support, insulation, and nourishment to neurons

Motor Neurons

Nerve Cells that transmit signals from the central nervous system to muscles, gland, and organs, initiating and controlling voluntary and involuntary movements

Sensory Neurons

Specialized nerve cells that transmit sensory information from nerve receptors to the CNS

Interneurons

Nerve cells that serve as connectors within the CNS, relaying signals between sensory and motor neurons

Reflex Arc

Neural Pathway that controls reflex actions, allowing for rapid, automatic reponses to sensory stimuli without conscious thought
