Major parts of the brain Crossword

Type
Crossword
Description

The cerebrum is the largest part of the brain in mammals. It is composed of the frontal, parietal, occipital, and temporal lobes. cerebrum
This lobe lies between the occipital bone and the parieto-occipital sulcus. It functions to receive and interpret visual signals. Occipital lobe
These are the shallow groves in the surface of the cerebrum. Sulci
This lobe lies between the temporal bone and the lateral sulcus. It functions in memory, vison, learning, hearing, and emotional behavior. temporal lobe
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, mood, foresight, motivation, and social judgements. frontal lobes
The spinal or nerve cord 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
These structures lie between the parietal bones and the central sulcus. They function in integration of sensory information with the exception of vision, hearing, and smell. parietal lobes
These are the thick folds in the surface of the cerebrum. gyri
The second largest part of the brain in mammals and the largest part of the brain in birds. The cerebellum is involved in the regulation of posture and balance, fine motor control of skeletal muscles, and repetitive movements. cerebellum
This fissure is a deep groove separating the cerebrum into right and left halves. Longitudinal fissure
An endocrine gland directly attached to the hypothalamus. It is divided into anterior and posterior portions. Anterior pituitary produce hormones which regulate other endocrine glands, and directly affects target cells. Posterior pituitary functions to store and release hormones produced by the hypothalamus. pituitary gland
The longitudinal fissure divides the cerebrum into right and left cerebral hemispheres. Cerebral hemisphere
The region that regulates the day/night cycle. Secretes the hormone motion melatonin, which effects sleepiness. pineal body
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
The part of the brain that contains the nerve tracts and physically joins the two cerebral hemispheres. Corpus callosum
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
A structure that processes olfactory information and contains centers for reflex movements involved in eating, such as chewing, licking, and swallowing. mammillary body
The medulla 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 region that is also called the “mesencephalon”. It is located above the pons and is the smallest part of the brain stem. The oculomotor, trochlear, and trigeminal cranial nerves originate in this area. midbrain
A structure that is located on the bottom-center of the brain where the two optic nerve cross. Optic chiasma
