Module 2 Flashcards
(34 cards)
Neurons
Allow communication throughout nervous system and body.
Neurotransmitters
pass from one synapse from to another. emotions and behavior are influenced
Cell body
energy is generated and info is collected for transmission to other neurons.
Synaptic receptors
embedded in the membranes of dendrites to receive chemical messages from the terminal of other neurons
Dendrites
receive chemical messages from other neurons.
Terminal
Chemical communications are sent out to other neurons here.
Axon
conveys info from the cell body to other neurons within the nervous system
Myelin Sheath
Speeds the transmission of neural impulses
Nucleus
Energy for cell is generated and waste products are eliminated.
Central Nervous System
Organizes and interprets the information from peripheral nervous system. Sends commands back to take actions
Brain
control system
Spinal cord
Relays messages to and from brain
Peripheral Nervous system
Connects the spinal cord to the body
Autonomic Nervous System
Controls involuntary actions
Parasympathetic Nervous system
Returns body to resting state after arousal
Sympathetic Nervous system
Arouses body to prepare for actions
Somatic Nervous System
Regulates voluntary motor actions
Forebrain
seat of thought, memory, decisions, planning, personality and emotion
Midbrain
Conveys visual and auditory information from spine to forebrain
Hindbrain
Controls bodily functions vital to life; contributes to regulation of sleep/
wakefullness
corpus callosum
connect left and right hemispheres of the brain
limbic system
regulate mood, emotion, memory and basic desires like thirst and hunger
Thalamus
gateway to higher functions
cerebral cortex
4 lobes. interprets sensory information, controls voluntary movement, home of higher cognitive processes.
