|
This is located in the vertebral foramen. It begins at the foramen magnum and ends at the conus medullaris in the lumbar region. It conducts sensory impulses to the brain and motor impulses from the brain to the body. |
spinal cord
|
|
|
This is the largest part of the brain in mammals. It is composed of the frontal, parietal, occipital, and temporal lobes. |
Cerebrum
|
|
|
These structures lie between the frontal bones and the central sulcus, and above the eye orbits. They have motor functions, but also deal with aggression, mode, foresight, motivation, and social judgments |
frontal lobes
|
|
|
These structures lie between the parietal bones and the central sulcus. They function in integration of sensory information with the excepting of vision, hearing, and smell. |
parietal lobes
|
|
|
This lies between the occipital bone and the parieto-occipital sulcus. It functions to receive and interpret visual signals. |
occipital lobe
|
|
|
This lies between the temporal bone and lateral sulcus. In functions on memory, vision, learning, hearing, and emotional behavior.
|
temporal lobe
|
|
|
These are the thick folds in the surface of the cerebrum.
|
gyri
|
|
|
These are the shallow groves in the surface of the cerebrum.
|
Sulci
|
|
|
This is a deep groove separating the cerebrum into the right and left halves |
Longitudinal fissure
|
|
|
The longitudinal fissure divides the cerebrum into right and left halves
|
cerebral hemispere
|
|
|
The second largest part of the brain in mammals and the largest part of the brain in birds. This is involved in the regulation of posture and balance, fine motor control of skeletal muscles, and repetitive movements.
|
cerebellum
|
|
|
This is directly attached to the hypothalamus. It is divided into anterior and posterior portions. The anterior portion produces hormones which regulate other endocrine glands, and directly affect target cells. The posterior portion functions to store and release hormones produced by the hypothalamus.
|
pituitary gland
|
|
|
This structure functions to integrate all sensory information (with the exception of smell) from the body, and channels it into proper processing regions in the cerebrum.
|
Thalamus
|
|
|
The structure that is the major integration system between various organ systems and the nervous system. It coordinates activities of both the nervous and endocrine systems, and between voluntary and autonomic activities. It is attached directly to the pituitary gland. |
hypothalamus
|
|
|
A structure that processes olfactory information and contains centers for reflex movements involvedin eating, such as chewing, licking, and swallowing.
|
Mammillary body
|
|
|
The region that relates the day/night cycle. Secretes the hormone melatonin, which effects sleepiness.
|
pineal body
|
|
|
The part of the brain that contains the nerve tracts and physically joins the two cerebral |
corpus callosum
|
|
|
A region that is also called the "mesncephalon". It is located above the pons and is the smallest part of the brain stem. The oculomotor, trochlear, and trigeminal cranial nerves originated in this area. |
Midbrain |
|
|
This is located just above the medulla, on the brain stem. It works with the medulla to control respiration and helps regulate sleep. It is the origin for the trigeminal, abducens, facial, and vestibulocochlear cranial nerves. |
Pons |
|
|
This is at the base of the brain stem. It contains nerve centers for the regulation of heart rate, blood vessel diameter, respiration, swallowing, vomiting coughing, sneezing, and hiccoughing. |
Medulla oblongata |
|
|
A structure that is located at the bottom-center of the brain where the two optic nerves cross |
Optic chiasma |
|
|
These are located just below the frontal lobes. They function in the sense of smell. |
Olfactory bulbs |
