describe The Function Of Hypothalamus And Thalamus. Flashcards
What is the hypothalamus?
It is the primary visceral control centre of the body.
What is it crucial to?
The hypothalamus is crucial for homeostasis.
What duty do the mammillary bodies perform?
The mammillary bodies act as relay stations in the olfactory pathways.
What does the hypothalamus control?
The hypothalamus controls the autonomic nervous system and the endocrine system function.
Why is the hypothalamus important to the limbic system?
The limbic system is the emotional part of the brain and the hypothalamus acts through the ANS pathways to initiate many physical expressions of emotion.
What other functions do the hypothalamus carry out?
The hypothalamus acts as the body’s thermostat, controls hormone secretion from the anterior pituitary gland whilst also producing other hormones such as antidiuretic hormone and oxytocin.
Where can the thalamus be found?
The thalamus is deep within the brain and makes up 80% of the diencephalon.
What is the purpose of the thalamus?
The thalamus processes and relays all incoming and outgoing information between the cerebral cortex and the spinal cord. The thalamus is also responsible for mediating motor activities, sensation, cortical arousal, learning and memory.
What is the outcome of an afferent being received?
When an afferent impulse is received the thalamus will basically recognise the impulse as either pleasant or unpleasant.
What information does the thalamus nuclei receive?
The thalamus nuclei also interpret instructions aiding in direction of motor cortical activity from the cerebellum and the basal nuclei.
