Hemispheres 3.0 - Level I Brain anatomy
and Physiology (Latest Update 2026 /
2027) Questions & Answers {Grade A}
100% Correct
Medulla Oblongata regulation of autonomic functions - correct answer respiratory
rhythm, heart rate, blood pressure
Medulla oblongata regulation of reflexes - correct answer swallowing, vomiting,
sneezing and coughing
What type of nerve fibers are in the medulla oblongata - correct answer both sensory
and motor nerve fibers
Where does medulla oblongata relay impulses - correct answer between brain and
spinal cord
Where is the site of pyramidal decussation - correct answer medulla oblongata
,Pyramidal decussation - correct answer where main motor tracts cross causing
muscles below the neck to be controlled by opposite sides of the brain
Reticular fomation - correct answer several small neural networks of gray matter with
white matter tracts ascending up to cortical structures and descending down to the
spinal cord
Reticular formation function - correct answer coordinates many vital and reflexive
functions
1. Ascending reticular activating system
Lateral reticular formation
Ascending reticular activating system - correct answer arousal and level of
consciousness
(damage here can result in loss of consciousness and progress to coma)
Lateral reticular formation - correct answer respiratory drive, heart rate, blood
pressure
,Thalamus location - correct answer paired structure on either side of the third
ventricle
Thalamus function - correct answer relay center for sensory information and some
motor pathways from the body to the cerebral cortex
Connects with reticular activating system and plays a role in the sleep-wake cycle
Hypothalamus location - correct answer below the thalamus and surrounds the lower
part of the third ventricle
Hypothalamus function - homeostasis - correct answer water balance, body
temperature, sexual activity, regulation of cardiovascular, and gastrointestinal activity
Hypothalamus function - hormone regulation - correct answer controls production and
release of hormones from the pituitary gland
, Basal ganglia function - correct answer Primary responsible for initiation of motor
movement
Basal ganglia - correct answer clusters of subcortical nuclei
Includes caudate and lenticular nuclei and areas associated with hemorrhage risk
Amygdala - correct answer Almond shaped mass of grey matter located in the
temporal lobe
Receives neuronal signals from the cerebral cortex and also connects to the
hypothalamus
Amygdala function - correct answer Involved with emotions and control of emotional
behavior
Helps relate to environment and expected behavior
Hippocampus - correct answer gray matter collection located under the temporal lobe
and shaped similar to a seahorse
