Module 4
The pitch of a sound is given by this part of the waveform
What is frequency?
Most mechanoreceptors have this type of primary afferent
What are A beta afferents?
This is the muscle type that takes care of voluntary movement
What is skeletal muscle?
This is the largest and longest spinal tract
What is the corticospinal tract?
This part of the pituitary mainly releases Oxytocin and ADH
What is the posterior pituitary?
The organ of Corti is found in this chamber of the cochlea
What is the Scala Media?
Facial sensation is primarily handled by this cranial nerve
What is the trigeminal nerve (CN V)?
This name refers to an alpha motor neuron and all of the muscle fibers it innervates
What is the motor unit?
This area is where the vestibulospinal tract initiates
What is the vestibular nuclei of the cochlea?
This part of the pituitary is made of glandular tissue
What is the Anterior Pituitary?
The apex of the basilar membrane encodes this type of frequency
What is low frequency?
This type of pain is primarily from an immune response
What is inflammatory pain?
This is a protein on actin that binds calcium during muscle contraction
What is troponin?
Brodmann's areas 5 + 7 are found in this lobe of the brain
What is the parietal lobe?
What is cortisol?
This is the primary thalamic area that is part of the auditory pathway
What is the MGN?
This mechanoreceptor has a large receptive field and handled high frequency vibrations of the subcuntaneous layer
What is the Pacinian Corpuscle?
In the stretch reflex, this proprioceptive organ is used to sense muscle length
What is the muscle spindle?
The indirect pathway of the basal ganglia uses this type of dopamine receptor
What is a D2 receptor?
Preganglionic cells of the parasympthetic division of the ANS are located in these two spinal areas
What are the brainstem and sacral spine?
When localizing a high frequency sound on the horizontal plane the difference of this aspect of sound is used
What is intensity (internaural intensity difference)?
This mechanoreceptor responds to stretch and is found in the dermis of hair skin
What are Ruffini Endings?
This is the type of interneuron that acts on the flexor muscle in this reflex
What is an excitatory interneuron?
The tectospinal tract decussates in this area of the brainstem
What is the midbrain?
What is the Basal Forebrain Complex?
