Neuro 8 Flashcards
What does the pituitary do?
It is the output of the hypothalamus (hormonal)
What is unique about the pituitary?
It has two distinct types of tissue
What kind of tissue is the posterior pituitary?
Neural tissue → it is an extension of the brain
What kind of tissue is the anterior pituitary?
Endocrine tissue
Where are major hormones released from?
Posterior pituitary
What are the major hormones released from the posterior pituitary?
Oxytocin and vasopressin
What is the cerebrum in terms of size?
Largest part of the brain
What does the gray matter in the cerebrum include?
Cerebral cortex, basal ganglia, and limbic system
What is referred to as the seat of intelligence?
Cerebrum
Why is the cerebrum the seat of intelligence?
It carries the ability to read, write, imagine predict (higher processes)
What is the corpus callosum?
Connects the 2 hemispheres of the cerebrum
What’s the major job of the basal ganglia?
Regulating the initiation and termination of movement (thought → movement)
What is involved in learning and memory?
Hippocampus
Where is the hippocampus located?

Hippocampus
What is the cerebral cortex?
Outermost layer of the cerebrum
What are sulci?
The indentations or grooves
What are gyri?
Folds or bumps in the brain
What are the 3 regions of functionality that the cerebral cortex is divided into?
Sensory areas
Motor areas
Association areas
What does the frontal lobe do?
Helps with skeletal muscle movement
What does the parietal lobe do?
Sensory association
-→ processes sense of touch and also helps you understand where you are in relation to other things around you
What is the occipital lobe associated with?
Vision
What is the temporal lobe associated with?
Hearing
How many lobes is each hemisphere divided into?
4
Is the distribution of functional areas in the two hemispheres symmetrical
No
What does it mean for the cerebral cortex to undergo plasticity?
It can change throughout life
