Cerebrum, Cerebellum, Brainstem
The three major parts of the brain
Largest part of the brain associated with higher mental functions
Second largest part of the brain that coordinates voluntary muscular activity
Gives rise to the thalamus, hypothalamus, and the epithalamus
Part of the spinal cord that consists of the medulla oblongata, pons, and the midbrain. Also coordinates and regulates visceral activities.
Seperates the two cerebral hemispheres
Seperates the two cerebellar hemispheres
Seperates the cerebrum from the cerebellum
Arteries that carry blood to the brain
Veins that return the blood from the brain
Protects brain from harmful substances
Helps maintain homeostasis and allows brain and spinal cord to communicate
Medulla oblongata, midbrain, reticular foramen, pons
The four parts of the brain stem
Transmits all ascending and descending impulses
Controlls heart rate in the medulla oblongata
Controlls blood pressure in the medulla oblongata
Regulates the rhythm of breathing in the medulla oblongata
Short section of the brainstem between the diencephalon and the pons
Thalamus, hypothalamus, epithalamus
Parts of the diencephalon
Heart rate, arterial blood pressure, body temperature, water and electrolyte balance, hunger, body weight, movements and secretions of the GI tract, sleep and wakefulness, growth and reproduction
7 things the hypothalamus regulates
Small region superior to the thalamus
Connects the two hemispheres of the cerebellum
Cerebellar white matter
Deep bridge of nerve fibers that connect the two cerebral hemispheres
Frontal,Parietal, Temporal, Occipital
The 4 lobes of the cerebral hemispheres
transmit intrahemispheric impulses
Transmit interhemispheric impulses
Transmit ascending and descending impulses
Frontal eye field
controls voluntary movements of the eyes and eyelids
reasoning, judjement, emotions, verbalizing ideas and storing memories
Funtions of the association areas
Masses of gray matter located deep within the cerebral hemishperes
Receiving and analyzing sensory imput
Function of the cerebral hemispheres
emotion,art,mental imagery (3D), music
Functions of the right cerebral hemisphere
Analytical problem solving, verbal
Functions of the left hemisphere

Abduction of the eyeball
Function of the Abductens nerve
Is the Facial nerve a motor, mixed, or sensory nerve?
Is the Vestibulocohlear nerve a sensory, motor, or mixed nerve?
Branch that carried impulses for equilibruim
Branch that carries impulses for hearing
Is the Glossopharyngeal nerve a mixed, motor, or sensory nerve?
Carry signals from the taste buds of the posterior one-third of the tongue
Function of the glossopharyngeal nerve
Is the Vagus nerve a motor, sensory, or mixed nerve?
Swallowing and Vocalization
Functions of the Vagus nerve
Is the Accessory nerve a mixed, motor, or sensory nerve?
Supplies nerves to the sternocloidmastoid and trapezius muscles to coordinate head movements
Function of the Accessory nerve
Is the Hypoglossal nerve a motor, sensory, or mixed nerve?
Conducts impulses for speech and swallowing
Function of the Hypoglossal nerve
