Definition
| Conduction Pathway between higher and lower brain centers. Visual and auditory reflex centers contain nuclei fro cranial nerves III and IV. Controls visual reflexes that coordinate head and eye movements when we follow a moving object |
|
|
Term
| Basal Nuclei/Basal Ganglia |
|
Definition
| Several patches of gray matter burried deep within the white matter of central hemisphere. Helps to regulate voluntary movement activity(skeletal muscles) Important in motor coordination |
|
|
Term
|
Definition
| Pathway between higher brain centers and spinal cord. Houses nuclei of cranial nerves VIII-XII. Ascending sensory pathways from skin and visceral nuclei controlling heart rate, blood vessels diameter, respiratory rate, vomiting, and coughing. Sensory relay to cerebellum. Autonomic reflex center involved in maintaining body homeostasis. |
|
|
Term
|
Definition
| Functional system that spans the brain stem; maintains cortical matter alertness and filters out repetitive stimuli. Regulates skeletal and visceral muscle activity. Keeps the cerebral cortes alert, conscious and enhances excitability. |
|

Term
|
Definition
| Relay information from cerebrum to cerebellum. Control respiratory rate and depth. Houses nuclei of cranial nerves V-VII. Contains the pneumatic center to maintain the normal rhythm of breathing. |
|

Term
|
Definition
| Sensory areas are responsible for the sensations of touch, temperature, pressure and pain involving the skin. Association areas function in understanding speech and in using words to express thoughts and feelings. |
|
|
Term
|
Definition
| Sensory Areas responsible for vision. Association Areas combine visual images w/ other sensory experiences. |
|
|
Term
|
Definition
| Motor Areas control movement of voluntary skeletal muscles. Association areas carry on higher intellectual processes such as those required for concentrating, planning, complex problem solving, and judging consequences of behavior. |
|
|
Term
|
Definition
| Sensory Areas responsible for hearing. Association areas interpret sensory experiences and remember visual scenes, music and other complex sensory patterns. |
|

Term
|
Definition
| Functional System involving cerebral and diencephanlon structures that mediates emotional response. Involved in memory processing. |
|
|
Term
|
Definition
| Integrates the autonomic nervous system. Regulates body temperature, food intkae, water balance, thirst and biological rhythms and drives. Regulates horomonal output of anterior pituitary glands. The main visceral control center of the body responsible for maintaining homeostasis. |
|
|
Term
|
Definition
| Processes information from cerebral motor cortex and from propriceptors and visual equlibrium pathways and provides instructions to cerebral motor cortex and subcortical motor center that result in proper balance and smooth skeletal muscle movement. |
|
|
Term
|
Definition
| Localizes and intreprets sensor inputs. Contains voluntary and skilled muscle activity and functions. Intellectual and emotional processing. Initiates skeletal muscle movements. |
|
|
Term
|
Definition
| Station for sensory impulses, passing upward to the sensory cortex. Sorts and edits information from sensory areas ascending to the cerebral cortex. |
|
|
Term
|
Definition
| Associated with the pineal gland. Secretes melatonin to induce sleep. |
|
|
Term
|
Definition
| provides a pathway for ascending and descendign tracts, control of vital activites, controls conscious and awake/sleep patterns by neurons of reticular formation. |
|
|
Term
|
Definition
| brings sensory information concerning the position of limbs, joints and other parts of the body to the cerebellum |
|
|
Term
|
Definition
| transmits a signal from the cerebral cortex to the cerebellum concerning the desired position of these parts. |
|
|
Term
|
Definition
| After intergrating and analyzing this information in this pair of nerve tract, the cerebellum sends impulses to the mid brain |
