Relays for sensory info.
Emotions,drives like hunger and thirst, hormones, homeostasis (hooks to pituitary).
Primary link between nervous and endocrine system.
Processes visual and auditory info and involuntary muscles; arousal from sleep, awareness, eating, sleeping attention.
Motor control, connects cerebellum to brain stem.
Regulates heart rate, blood pressure, respiration and digestion, connects brain to spinal cord; vital centers.
Largest region of the brain, contains: conscious thoughts, sensations, intellect, memory and complex movements (many divisions called lobes).
SOMATIC MOTOR ASSOCIATION AREA;-
Cerebrum lobe that Coordinates learned movements, speech.
PRIMARY MOTOR CORTEX;-
Cerebrum lobe that directs voluntary movements to motor neurons.
PRIMARY SENSORY CORTEX;-
Cerebrum lobe that receives sensory input: touch, pressure, pain and temperature.
Cerebrum lobe that taste, predicts future consequences of actions, abstract intellectual functions, feelings of frustration, tension and anxiety.
Cerebrum lobe that sensory analysis of your body in space, processes external sensory input; allows you to recognize a touch as light as a mosquito on your skin.
Cerebrum lobe that visual processing and visual memory.
Cerebrum lobe that hearing, memory of sounds, speech, and understanding speech.
Timing, coordination, stored memories.
Where optic nerves cross.
Used for feeding reflexes and behaviors.
Joins the two hemispheres of the brains allowing communication.
Controls Circadian Rythms (serotonin).
Pain, emotional behavior and anticipation.
Divides left and right cerebral hemispheres.
Important processing center and relay station for info headed to or from cerebrum or cerebellum.
Supports brain and transports nutrients, chemical messengers, and wastes.
CENTRAL NERVOUS SYSTEM;-
Brain and spinal cord.
PERIPHERAL NERVOUS SYSTEM;-
Everything except brain and spinal cord; divided into Somatic Nervous Sytem and Autonomic Nervous System.
SOMATIC NERVOUS SYSTEM;-
Part of Peripheral Nervous System that moves skeletal muscles.
AUTONOMIC NERVOUS SYSTEM;-
Part of Peripheral Nervous System that moves smooth/cardiac muscles and affects fat and glands.
Neuron cell bodies (lines outside of brain).
Neuron axons (inside of brain).
Aka glial cells; support neurons by regulating environment and destroying pathogens; several types exist.
Afferent; pick up on external or internal environments
ex: taste, pain. touch.
Efferent; cause movement of smooth, skeletal, or cardiac muscle.
Only in brains and spinal cord; link nerves in reflex arch, may play a role in memory.
Part of neuron that receives message.
Part of neuron that contains organelles.
Part of neuron that clusters rough ER and free ribosomes; makes cell body appear gray.
Part of neuron that continues messages to synaptic terminals.
