Primary Visual Area is to _______;
Primary Auditory Area is to ______.
Striate Cortex; Heschl Gyrus
Which tract is primarily responsible for transmitting sensory information related to pain and arousal to the reticular formation in the brainstem?
Spinoreticular tract
What are the cranial nerves that are responsible for gustation?
Vagus
Glossopharyngeal
Facial
Chemical Energy is the stimulus for Olfaction because of smell.

A system demonstrating a hierarchical organization is one in which
Each element has specific levels or ranks with respect to one another.
The sensory organs of the vestibular system
help a person to maintain balance.
As humans get older, poorer acuity of the vision is due to the following except:
Conjunctivitis
Which structure contains the receptors of the vestibular system?
semicircular canals
Conscious Proprioception is to __________;
Pain and temperature perception is to______
Dorsal Column Medial Lemniscal Tract;
Spinothalamic Tract
Somatosensory information is carried to the cortex via two major pathways that
share some overlap of function
Retina is to _______; __________ is to Audition.
Vision; Organ of Corti
Which of the following is NOT considered a gustatory function?
People don’t like Okra because they are slimy.
The emotional response to odor is to _______.;
The conscious reaction to odors is to_____.
Limbic System;
Orbitofrontal Cortex
Which statement accurately reflects the cortical representation of pain in the brain?
Despite the involvement of multiple brain regions, pain lacks a distinct cortical representation.
Areas of neocortex that receive most of their input from the thalamic relay nuclei of one sensory system are classified as
primary sensory cortex.
Which of the following disorders happen when the lenses of the eye turn opaque?
Cataract
Each cortical level of a sensory system (primary, secondary, or association) is itself composed of different areas that mediate different processes. This pattern of sensory system organization is referred to as
functional segregation.
Which brain region is primarily responsible for the conscious perception and evaluation of odors?
Orbitofrontal Cortex
The diameter of the different segments of the spinal cord is not the same.
This is because some segments supply a larger area of the body compared to the rest.
Both True
Which of the following is NOT a function involving the external sensations?
Thinking about what will be your goal in 5 years time.
It is the area of body innervated by left and right dorsal roots of a segment of spinal cord.
Dermatones
Chemical Energy is to _______; _________ is to Gustation.
Olfaction; Chemical Energy
The spinal nerves cover the somatosensory function from head to toe.
Spinal nerves contain both motor and sensory nerves.
False; from BODY to toe
True
Which nucleus serves as a primary relay station for gustatory information
Solitary Nucleus
The loudness, pitch, and timbre of a sound are directly related to the __________, respectively, of the vibrations that produced it.
Amplitude, Frequency, Complexity
Which structure contains the receptors of the vestibular system?
Semicircular canals
The simple process of detecting the presence of stimuli is often referred to as
Sensation
Morse Type:
Comprises two main parts: the medial superior olives (MSO) and the lateral superior olives (LSO).
A. Superior Olives
B. Superior Colliculus
A
The olfactory nerve sends impulses to the
Piriform cortex
One of the Covid-19 symptoms is the inability to smell. Which is true regarding how our olfactory sense is damaged?
The olfactory receptor cells scattered in the nasal cavity were damaged due to infection.
The frequency of sound waves is to the complexity of sound waves as the
the pitch of the sound is to the timbre.
The sense of touch is largely
Exteroreceptive
Prosopagnosia refers to the inability to recognize faces, even those of familiar individuals such as friends and family members
True
Which region of the auditory cortex is primarily involved in basic auditory processing?
Core region
The auditory system is organized
Tonotopically
According to the former model of sensory system organization, sensory processing is characterized by parallel streams dedicated to specific sensory inputs.
False; CURRENT model
What is the correct pathway that soundwaves travel from the external world to the inner ear
hammer – anvil – oval window – cochlea – auditory nerve
The sensory pathway ends in the receptor.
It converts the energy to nerve impulses.
Both TRUE
The semicircular canals are the receptive organs of
Vestibular system
A system in which information is conducted in a single route through its various components, like a string through beads, is called a
Serial system
The auditory cranial nerves enter the brainstem, specifically the _______
Pontomedullary junction.
Modern neuroscientific theory considers sensory systems to be
hierarchical, functionally segregated, and parallel.
Which somatosensory structure does not receive substantial input from the anterolateral system?
Dorsal column nuclei
Which nucleus serves as a primary relay station for gustatory information?
Solitary nucleus
As one ages, loss of sensitivity to high-pitched sounds occurs.
This is why you should speak louder and at a higher pitch to trigger a response.
F
T
Resting on the auditory hair cells is the
Tectorial membrane
An area of cerebral cortex that receives substantial input from more than one sensory system is classified as
Association cortex
The Ventral Parietal lobe is the _______.
The Piriform and peri-amygdaloid cortex are the______
Primary Gustatory Cortex;
Primary Olfactory Cortex
The auditory fibers moves contralaterally in the _______.
Midpons
The primary auditory area is arranged based on ______.
Hertz
