4 Regions of the Inner Cerebrum:
Hint: PACT & CC |
Projection tracts
Association tracts Commissural tracts Corpus Callosum |
|
nerve fibers that carry either DESCENDING nerve impulses from the cerebral cortex to other REGIONS of the brain and spinal cord or ASCENDING nerve impulses from the spinal cord and LOWER regions of the brain to cerebral cortex.
Hint: PT |
Projection tracts
|
|
nerve fibers that CONNECT various areas of the cerebral cortex
within the same cerebral hemisphere. HInt: AT |
Association tracts
|
|
nerve fibers that CONNECT the right and left cerebral HEMISPHERES
Hint: CT |
Commissural tracts
|
|
makes possible the exchange of inforMAtIoN in the form of
|
Corpus Callosum
|
|
Motor Functions of the Cerebral Cortex
Hint: MSA |
Motor
Sensory Association |
|
neurons in this AREA control the conscious and PRecIse
voluntary contractions of skeletal MUSCLES. |
Primary Motor Area
|
|
neurons in this AREA cause groups of MUSCLES to contract in a specific SEQUENCE, thereby producing stereotyped movements.
Hint: PreMA |
Premotor Area
|
|
motor area associated with the ability to speak- found only in the left cerebral hemisphere in most individuals.
Hint: Boca |
Broca's Area
|
|
neurons in this AREA function as Interpretation centers for the general SENSES.
Hint: PSA |
Primary Sensory Area
|
|
neurons in this area function as the interpretation center for the sense of vision
|
Visual Area
|
|
neurons in this area function as the interpretation center for the sense of hearing.
|
Auditory Area
|
|
neurons in this area function as the interpretation center for the sense of smell.
|
Olfactory Area
|
|
neurons in this area function as the interpretation center for the sense of taste.
|
Taste Area
|
|
considered to be the site of higher INTELLECTUAL abilities that are characteristic of humans.
|
Frontal Association Area
|
|
What are the 3 motor functions of the cerebral cortex?
Hint: PPB |
Primary Motor Area
Premotor Area Broca's Area |
|
What are the 5 sensory functions of the cerebral cortex?
Hint:PVOAT |
Primary Sensory Area
Visual Area Auditory Area Olfactory Area Taste Area |

What is the only association function of the cerebral CORTEX?
|
Frontal Association Area
|
|
What are the structures of the Brain?
Hint: BCCD |
Cerebrum
Diencephalon Cerebellum Brain Stem |
|
Parts of the Diencephalon:
Hint: TP HELP |
Thalamus
Hypothalamus Epithalamus Pineal Gland Limbic System Pituitary Gland |
|
MAIN SENSORY relay center between the brainstem and cerebral cortex.
|
Thalamus
|
|
REGULATES the pituitary; source of HORMONES such as ADH and
oxytocin; and integration center for temperature regulation, hunger, sex drive, and emotions such as fear and rage. |
Hypothalamus
|
|
contains the choroid PLExUS of the third ventricle.
|
Epithalamus
|
|
main source of hormone MELATONIN.
Hint: SLEEP |
Pineal Gland
|
|
a GROUP of structures that collectively pLay a role In eMotional responses.
|
Limbic System
|
|
Pituitary Gland (hypophysis)- 2 organs attached:
Hint: A&N |
Adenohypophysis
NeuroHypophysis |
|
NOT of neural origin.
|
Adenohypophysis
|
|
OF neural origin.
|
Neurohypophysis
|
|
function of the Pituitary Gland
Hint: P&S |
production and secretion of several hormones
|
|
Parts of the Cerebellum:
Hint: VAV |
Vermis
Arbor Vitae |
|
structure that connects the 2 cERebellar heMISpheres.
|
Vermis
|
|
white matter or nerve TRACTS of the cerebellum.
|
Arbor Vitae
|
|
functions of cerebellum -
|
the subconscious coordination of skeletal muscular activities - also involved with the sense of EQUILIBRIUM.
|
|
Parts of the Brain Stem:
Hint: MRP |
Medulla Oblangata
Reticular Activating System Pons |
|
contains VITAL reflex CENTERS such as cardiac control center,
respiratory control center, and vasomotor center. |
Medulla Oblongata
|
|
an ACTIVATING or arousal SYSTEM that is essential in
maintaining WAKEfulness. |
Reticular Activating System
|
|
contains nerve tracts that CONNECTS the CEREBELLUM with brain STEM and nerve tracts that connect upper and lower levels of CNS - also contains pneumotaxic and apneustic centers that modify respiratory rate.
|
Pons
