|
What are the 4 parts of the diencephalon and a very description of what they do?
|
Thalamus-relay center
Subthalamus Epithalamus- contains pineal body, habenular nuclei responds to olfactory stimulation Hypothalamus- maintains homeostasis, regulates endocrine function |
|
|
What are the 3 function groups of the thalamus?
What do they do? |
Relay nuclei-subdivided into sensory relay and motor relay-convey information to the cerebral cortex
Association Nuclei-process emotional and memory info as well as integrates different types of info. Nonspecific Nuclei: regulates consciousness, arousal, and attention |
|
|
How is the subthalamus important to ODs?
|
it is associated with basal nuclei which are involve in motor control including EOMs.
|
|
|
Where is the habenular nuclei and what does it do?
|
epithalamus, it is involved in the emotional response to odor.
|
|
|
Where is the pineal gland and what does it do?
|
epithalamus, plays role in onset of puberty. Influences sleep wake cycle(circadian rhythms).
After age 17 it is opaque in x-rays |
|
|
Where are the mammilary bodies and what do they do?
|
posterior surface of the hypothalamus. Involved in emotional response to odor, memory, and sense of direction
|
|
|
What is the infundibulum?
|
stalk connecting hypothalamus and the pituitary gland
|
|
|
Generally speaking which portions of the hypothalamus stimulate the ANS?
|
Anterior -> Parasympathetic
Posterior-> sympathetic |
|
|
Which part of the pituitary releases neurohormones?
|
Posterior pituitary. This structure is continuous with the brain because it's cell bodies are located in the hypothalamus.
|
|
|
Explain how the hypothalamus triggers hormone release in the posterior and anterior pituitary.
|
Posterior- an action potential from the HT causes a release of neuro hormones into the bood stream
Anterior- neurohormones release from HT and travel via blood to the anterior pit. in response the ant pit secretes hormones. |
|
|
What are the neurohormones secreted by the posterior pituitary?
|
Antidiuretic Hormone (ADH)- regulate extracellular fluid
Oxytocin- fetus discharge in child birth |
|
|
What are 2 actions that will cause an increase in ADH release?
|
lack of water intake
decrease in blood pressure |
|
|
Name the 8 pituitary hormones
|
FSH-follicle stimulating H
LH-Luteinizing H ACTH-Adrenocorticotropic GH-Growth H ADH-Antidiuretic H TSH-Throid Stimulating H O-Oxytocin P-Prolactin |
|
|
Name 8 functions of the limbic system
|
Emotion
Memory Autonomic response to smell, emotion, mood, and other functions Motivation Mood Sensations of pain/pleasure Reproduction Nutrition |
|
|
What structures are involved with emotion?
|
amygdala, anterior cingulate cortex, orbitofrontal cortex, areas in the hypothalamus, anterior nuclei of the thalamus
|
|
|
What are the 3 types of memory discussed in class?
|
Emotional memory(strong)
Declarative memory(recalling facts etc.) Proceduarl memory |
|
|
What are the 3 stages of declarative memory and how long do they last?
|
Immediate Memory- 1-2 seconds- not in limbic system
Shortterm memory- lost around 1 minute. Long term- occurs after short term is processed. |
|
|
What are the 3 stages for learning a skill?
|
Cognitive- person is trying to understand the task, may have to talk themselves through it.
Associative- person refines movements to what they find to be most effective. Autonomous- movements are automatic, requires no attention. |
