Nervous system - Brain Flashcards
What is the lowest section of the brainstem called?
Medulla oblongata
What does the medulla oblongata control?
Heart rate and blood pressure, breathing and vomiting
What is the central section of the brainstem?
pons
What is the topmost part of the brainstem?
Midbrain
What is the channel within the midbrain?
The cerebral aqueduct that connects fourth and third ventricle
What is the function of the channel within the midbrain?
Relay signals for pain, movement, hearing and vision
What is the function of the pons?
Regulating of functions carried out by the cranial nerves
A critical role in generating the respiratory rhythm of breathing
What are the four parts of the Diencephalon?
Thalamus, Subthalamus, Hypothalamus and epithalamus
What is the function of the thalamus?
Relay sensory and motor signals to cerebral cortex, regulating of conscious awareness
What is the function of the hypothalamus?
Maintains homeostasis
Links nervous system to endocrine system via pituitary gland
What is the function of the subthalamus?
Motor function
What are the two subdivision of the epithalamus?
Pineal gland and habenular nuclei
What is the function of the pineal gland in the epithalamus?
Secretions play a role in circadian rhythms
What is the function of the habenular nuclei in the epithalamus?
Regulating serotine and dopamine, with roles in sleep, pain, stress and anxiety
What is the function of the frontal lobe?
Controls movement, speech, emotions, problem solving and memory
