HGD Exam 1 Questions with Correct Answers
Receptor
Recieves the stimulus
Afferent nerve
Carries signal to spinal cord/brain
Center
Processes the signal
Efferent nerve
Carries command back
Effector organ
muscle/gland that reacts
By Origin, By Center, By Purpose
What are the classification of reflexes?
Inborn
already there since birth, automatic
Learned
having much knowledge acquired by study.
Cerebellar
related to the cerebellum, a "little brain" located at the back and bottom of the skull
responsible for coordinating movements, balance, posture, and muscle tone
, Cortical
-the higher-level mental processes and cognitive abilities.
-memory, learning, language, complex perception
midbrain
a critical processing and relay center within the brainstem, managing sensory information
(vision and hearing), motor control (especially eye movements), and serving as an
"information superhighway" by transferring neural signals between the forebrain and
hindbrain
medullary(medulla oblongata)
regulates essential involuntary bodily functions such as breathing, heart rate, blood pressure,
swallowing, and coughing
Spinal
carrying motor commands for movement, relaying sensory information (like touch and pain),
and managing rapid, involuntary reflexes to allow for faster responses than would be possible
if the signal had to go to the brain first
Protective
protects us from danger
Posture
helps us stand and not fall.
Regulation
keep the body normal
