Part 2 Flashcards
The diencephalon links the _____________ with the rest of the _________ _________. It includes the
_________ and the _____________.
cerebrum; brain stem
thalamus and hypothalamus
is called the “gatekeeper” for the cerebrum.
Also part of limbic system.
What does that mean and why is it
important?
Thalamus
because it only sends small portion of info
The ____________ is integral in thermoregulation because it sets the body’s hypothalamic set point.
Understand what that means and what happens when the set point is raised or lowered.
Hypothalamus
The hypothalamus controls hormone production and release in the __________ gland (a major
___________ gland).
Pituitary gland
-a major endocrine gland
The hypothalamus is connected to the above gland via the ______________. This interphase between
the nervous and endocrine system is called the ___________-___________ axis.
infundibulum;
hypothalamic pituitary axis
Blinking and pupil dilation/constriction are controlled by what part of the brainstem?
midbrain
connects the cerebellum to the brainstem. Pay attention to what parts are being connected!!!!!!!
Pons
the apneustic and pneumotaxic centers are located in the _____________. Their function is to modify
the activity of the _______________ _____________ ____________ and so adjust respiratory rate and
depth.
respiratory rythmicity center
the medulla oblongata contains what centers?
-Cardiac center
-Vasomotor center
-Respiratory center
The cardiac center
adjusts the Heart Rate and strength of Contraction
the heart.
- The Vasomotor center adjusts
vessel diameter
The respiratory rhythmicity center
sets the basic respiratory pace
* Vomiting, coughing, hiccupping, swallowing, sneezing
The large, branches cells that make up the cerebellar cortex are _______________ cells. These cells are
highly branched. What is the significance of this?
Purkinje cells
The major function of the cerebellum is to coordinate _______________ body movements. It does this
by monitoring and comparing what our _________ with our _____________. Then adjusting future
contractions to allow us to perfect “learned movements” like walking, running, dancing, etc
Coordinate REPETITIVE body movements
The limbic system or “____________ brain”
The limbic system or “____________ brain” functions to:
- Establish emotional states and decide how we show emotions
- Provide motivational drives via the gratification center and aversion center (understand
what this means) - Facilitate memory storage and retrieval
The hippocampus is a “__________ _________” that can organize memories as they
occur. Can it store memories long term?
“Fast Learner”
No, does not store long term memory, gives it to cerebral cortex for long term storage
The cerebral cortex is a “_________ _________” that requires memories to be
“uploaded” numerous times before the memory is stored. Can it store memories
long term?
“Slow Learner”
Yes, the cerebral cortex “uploads” the memory and files it in long term storage.
Anterograde amnesia:
-no ability to organize INCOMING info
- inability to create new memories after an event
Retrograde amnesia:
-cant remember anything from the past
- inability to access memories or information from before an injury or disease occurred
Controls conscience thought and intellectual functions, processes incoming sensory
info, sends outgoing voluntary motor commands.
Cerebral cortex or neural cortex
lobes of cerebrum
frontal lobe
parietal lobe
occipital lobe
temporal lobe
what are the cerebrum sulcus
- Central sulcus divides:
* Frontal lobe from Parietal lobe - Lateral sulcus divides:
* Frontal lobe from Temporal lobe - Parieto-occipital sulcus divides:
* Parietal lobe from Occipital lobe
what hemispheric lateralization means and the clinical impact of this.
Each cerebral hemisphere receives sensory
information from, and sends motor commands to,
the opposite side of the body
