Flashcards in The Nervous System Deck (25):
Receives and transmits information.
Central nervous system
Consists of the brain and spinal cord. The brain is split into right and left hemispheres, which exhibit contralateral control and lateralization. The three major parts of the brain are the hindbrain, midbrain, and forebrain.
The top part of the spinal cord; includes the medulla, pons, and cerebellum.
Controls basic biological functions, such as breathing, swallowing, and balance.
Controls facial expressions, sleep, dreaming.
Controls fine motor movements.
Coordinates basic movements with sensory information.
Large in humans; includes the cerebral cortex and subcortical structures such as the thalamus, hypothalamus, and basal ganglia.
Regulates muscle contractions and movements.
Incorporates and relays sensory information to the cortex.
Controls motivated behavior, such as eating, drinking, and sex.
Helps process and receive long term and spatial memory.
Controls emotion and valuation of stimuli.
Receives sensory information and transmits motor information.
A nerve tracts beneath the cortex that connects the two hemispheres of the brain and allows them to communicate.
An area of the cortex located directly behind the frontal lobe. It's functions include: processing sensory information from body parts, which includes touching, locating positions of limbs, and feeling temperature and pain; and carry out several cognitive functions, such as attending to and perceiving objects.
Control speech, learning, thinking, decision-making, and abstract thought.
Peripheral nervous system
Includes all nerves that spread through the body from the brain and spinal cord. The peripheral nervous system has two divisions.
Controls voluntary muscle movements and sense organs.
Controls involuntary actions and the internal organs; divided into two parts.
Sympathetic nervous system
Gets the body ready for emergency action.
Parasympathetic nervous system
Becomes active during states of relaxation.
