Organization & Development Flashcards
FRONTAL LOBE:
HAS PRECENTRAL GYRUS WHICH CONTROLS VOLUNTARY MOVEMENT; PERSONALITY; CONCENTRATION; VERBAL COMMUNICATION; PLANNING & DECISION MAKING
PARIETAL LOBE:
SOMATOSENSORY CORTEX WHICH CONTROLS SENSORY OF TOUCH
TEMPORAL LOBE:
HEARING AND SMELL
OCCIPITAL LOBE:
VISION
INSULA LOBE:
SMALL AND DEEP TO THE TEMPORAL LOBE; CONTROLS MEMORY AND TASTE
Name the lobes.
Frontal, parietal, temporal, occipital, and insula
What are the four major brain regions?
CEREBRUM, CEREBELLUM, BRAIN STEM, DIENCEPHALON
What is the corpus callosum?
CONNECTS THE HEMISPHERES OF THE BRAIN AND IS THE MAIN METHOD OF COMMUNICATION BETWEEN THEM
What is the longitudinal fissure?
DEEP MIDSAGITTAL GROOVE THAT SEPARATES THE CEREBRAL HEMISPHERES
Know the embryonic structure that develops into the CNS.
ECTODERM
What are the cranial and caudal neuropores?
(DURING EMBRYONIC DEVELOPMENT) CRANIAL NEUROPORE: OPENING OF NEURAL TUBE CLOSEST TO THE FUTURE HEAD. CAUDAL NEUROPORE: OPENING CLOSEST TO THE FUTURE BACK
Define sulci.
SHALLOW DEPRESSIONS BETWEEN GYRI
Define gyri.
FOLDS OF BRAIN TISSUE
Diencephalon.
DEEP TO THE CEREBRUM; CONTAINS THALAMUS, HYPOTHALAMUS, AND EPITHALAMUS
Understand the difference between white matter and gray matter.
GRAY MATTER: TYPICALLY LINES THE OUTSIDE OF THE BRAIN AND INSIDE OF THE SPINAL CORD.
Describe the arrangement of white and gray matter in the brain.
GRAY: CEREBRAL CORTEX, CEREBRAL NUCLEI. WHITE: CORPUS CALLOSUM, INTERNAL CAPSULE
Describe the arrangement of white and gray matter in the spinal cord.
GRAY: INNER GRAY MATTER. WHITE: OUTER WHITE MATTER
What does the pineal gland produce?
MELATONIN
Describe role the of the thalamus with incoming sensory information.
GRAY MATTER; TELLS WHERE SENSORY INFO IS COMING FROM (INCOMING INFO MAY COME FROM THE EYE, THE FINGER, TOE, ETC.)
What is gray matter composed of? What does it do?
Dendrites and cell bodies; processing and integrating nerve info
What is white matter composed of? What does it do?
Bundles of myelinated axons; relaying nerve signals to/from gray matter
