Anatomy and Physiology V Flashcards
(25 cards)
What happens when the ventromedial area of the hypothalamus is destroyed?
Hyperphagia (p.414)
Name one cause of ventromedial hypothalamic destruction (p.414)
Craniopharyngioma (p.414)
What stimulates the ventromedial area of the hypothalamus?
Leptin (p.414)
What is the principle difference between the functions of the anterior and posterior hypothalamus?
Anterior mediates cooling which is a parasympathetic function; posterior mediates heating which is a sympathetic function (p.414)
From where does the posterior pituitary receive its input?
Receives hypothalamic axonal projections from supraoptic (ADH) and paraventricular (oxytocin) nuclei (p.414)
What is another name for the posterior pituitary?
Neurohypophysis (p.414)
What is another name for the anterior pituitary?
Adenohypophysis (p.414)
Name the five thalamic nuclei.
VPL, VPM, LGN, MGN, VL (p.415)
What are the inputs of the VPL of the thalamus?
Spinothalamic and dorsal columns/ medial lemniscus (p.415)
What are the inputs of the VPM of the thalamus?
Trigeminal and gustatory pathway (p.415)
What is the input of the LGN of the thalamus?
CN II (p.415)
What are the inputs of the MGN of the thalamus?
Superior olive and inferior colliculus of tectum (p.415)
What is the input of the VL of the thalamus?
Basal ganglia (p.415)
What type of information travels through the VPL nucleus of the thalamus?
Pain and temperature; pressure, touch, vibration, and proprioception (p.415)
What type of information travels through the VPM nucleus of the thalamus?
Face sensation and taste (p.415)
What type of information travels through the MGN nucleus of the thalamus?
Hearing (p.415)
What type of information travels through the LGN nucleus of the thalamus?
Vision (p.415)
What type of information travels through the VL nucleus of the thalamus?
Motor (p.415)
To where does information from the VPL nucleus of the thalamus travel?
Primary somatosensory cortex (p.415)
To where does information from the VPM nucleus of the thalamus travel?
Primary somatosensory cortex (p.415)
To where does information from the LGN nucleus of the thalamus travel?
Calcarine sulcus (p.415)
To where does information from the MGN nucleus of the thalamus travel?
Auditory cortex of the temporal lobe (p.415)
To where does information from the VL nucleus of the thalamus travel?
Motor cortex (p.415)
What is the function of the limbic system?
The limbic system is a collection of neural structures involved in emotion, long term memory, olfaction, behaviour modulation, and autonomic nervous system function (p.415)
