Unit 6b Flashcards
4 Regions of brain (BCCD)
- Brainstem (midbrain, pons, medulla oblongata)
- Cerebrum - largest (at top)
- Cerebellum - most neurons (at base)
- Diencephalon - between crerubrum and mdibrain)
gyRi are __ of the brain
Ridges
Suchi are _ of the brain
stems
Longitudinal fissue is a deep _ that divides the _ into left and right hemispheres
deep groove
divides cerebrum
Corpus callosum is a bundle of _ that connects the left and right _
bundle of NERVES
connects left & right HEMISPHERES
Gray matter is _ of the brain: responsible for _
surface
learning
White matter is underneath the _ _
cerebral cortex
Two mater has two layers. The P_ later is attached to _;
The M_ layer covers the _
Periosteal - attached to SKULL
Meningeal layer covers the BRAIN (continues to spinal later)
SUBDURAL space separates the dura mater from the a_ mater
Arachnoid
SUARACHNOID space spearates the archnoid mater from the p_ mater
pia
CerebroSPINAL fluid fills the the v_ and the c_ canal. It also bathes _ (inside or outside) of brain and spinal cord
ventricles
and central canal
bathes OUTSIDE of brain
Blood brain barrier are formed as a_cytes wrap around c_
ASTROCYTES wrap around CAPILLARIES
Blood brain barrier p_ brain from foreign substances
protects
MIDBRAIN is part of brain stem which relays SENSORY and MOTOR i__:
MIDBRAIN also has auditory and visual r_ and clusters of n_ important for muscle growth
impulses
audio and visual REFLEXES
clusters of NEURONS
PONS is part of the brain stem that contains tracts that convey s_ to and from diff parts of brain
conveys SIGNALS
MEDULLA OBLONGATA is part of the brain stem that controls the c_ center, the v_ center, and 2 r_ centers
cardiac
vasomotor
repiratory
CEREBELLUM monitors body m_ (balance posture) so m_ can work together.
Cerebellum also evaluates s_ input
movement
muscles
sensory input
THALAMUS is part of the diencephalon that process s_ input and decides which ones to transmit to cerebral cortex.
The THALUS also is involved in m_ and e_
sensory
memory & emotion
HYPOTHALAMUS is part of diencephalon that controls the automatic N_ system and the centers for HUNGER/THIRST/TEMP.
HYPTHALAMUS also controls the p_ gland
plays role in E_ responses (fear, anger, agression, stress)
nervous system
pituitary gland
emotional responses
The lobe that controls voluntary movements, memory, emotion, judgment, reasoning, agression is the _ lobe
FRONTAL
The lobe that controls HEARING, SMELL, LEARNING, MEMORY, EMOTIONAL BEHAVIOR, VISUAL RECONGITION is the _ lobe
temporal lobe
The lobe that controls bodily sensations and PROPRIOCEPTION (awareness of body in space) is the _ lobe
PARIETAL lobe
The lobe that controls VISION & Visual info is the _ lobe
OCCIPITAL
The lobe that controls PERCEPTION, MOTOR CONTROL, COGNITIVE FUNCTION and SELF_AWARENESS is the _ lobe
INSULA/ (orNSULAR
The Limbic system is the e_ brain and it contains the H_ and the A_
EMOTIONAL brain
contains Hippocampus & Amygdala
The Hippocampus is part of limbic system that converts _ memory to _ memory
short term memory
TO
long term memory
the AMygdala is part of the limbic system that stores and recalls e_ from past and present events
EMOTIONS
_ hemisphere has language, analysis, logic, science, math, controls RIGHT side of body
left
_ hemisphere is big picture, emotion, creativity, imagination and controls the LEFT side of body
right
Nerve 7 of the cranial nerve is the f_ nerve (taste, expression, tears)
N7 = facial
Nerve 8 of the cranial nerve is the v_nerve (hearing and balance)
N8 = VEStibULAR-cochLEAR
Nerve 9 of cranial nerve is the GLOSSOPHARYNGEAL nerve for t_ movemetns and blood pressure regulation
Nerve 12 is the HYPOGLOSSAL nerve for t_ movements
N9 and 12: tongue movements

Automatic Nervous System
1. Regulates activities that maintain homeo_
2. sends impulses to c_ and s_ muscles
Also called the v_ motor sytem
- maintain HOMEOSTASIS
- to CARDIAC & SMOOTH muscle
also called VISCERAL motor system
Automatic Nervous system is divided into
(1) the SYMPATHETIC : prepares body for a_
(2) PARASYMPATHETIC; c_ the body
activity
calms
