Pysch Quiz 5 Flashcards
Types of Neurons
Sensory neurons, Interneurons, motor neurons
Sensory neurons
Sense info and Carry signals back to brain
Interneurons
Make decisions based on where it goes next
Motor neurons
Connect the brain back to body and connect to muscle and glands to control what we do next
Peripheral nervous system
Somatic NS and Autonomic NS
Central nervous system
Brain and Spinal cord
Peripheral Nervous system
Consists of nerves that connect muscles, organs and glands to the central nervous system (Somatic NS and Autonomic NS)
Somatic NS
carries signals between the CNS and muscles in the body that control movement
Autonomic NS
carries signals between the CNS and organs/ glands that regulate involuntary actions and the body’s internal state (composed of Sympathetic NS
Parasympathetic NS)
Sympathetic NS
readies the body for action, increases heart rate, dilates pupils, inhibits digestion,
(“Fight or Flight”)
Parasympathetic NS
active during rest, Slows heart and breathing rates, stimulates digestion (“Rest and digest”)
Spinal cord
Carries sensory information to the brain, and motor control commands back to the body and Manages simple reflexes and movements
Brainstem
consists of medulla, pons and midbrain
Medulla
helps regulate heart rate and breathing
Pons
involved in maintaining balance, and walking
Midbrain
involved in modulation of motor activity
