Psychology - Sensory and Somatosensory Systems - MCAT Practice Questions
What is the term for the physical representation of the somatosensory cortex
that reflects the body's sensory sensitivity? Sensory Homunculus
The Somatosensory Cortex, which is responsible for receiving all sensory
input from the body, is located in which lobe of the cerebrum? Parietal Lobe
Which type of Physical Pain is directly caused by a potentially harmful
stimulus, such as touching a hot stove or sustaining a cut? Nociceptive pain
Pain : Pain that is caused by damage or disease affecting the somatosensory
nervous system itself (often described as shooting or burning) is classified
as: Neuropathic pain
The sense by which an organism perceives temperature, or more accurately,
infers temperature differences, is formally called: Thermoreception
If a patient reports a chronic, tingling sensation that follows the path of
a damaged nerve, this is a clear indication of which type of pain? Neuropathic pain
What is the name of the specialized epithelial tissue inside the nasal
cavity that contains the receptor cells for the sense of smell? Olfactory Epithelium Function
The Olfactory Bulb Function involves sending projections through which
structure to reach the olfactory epithelium? Cribriform plate
What are the structures within the Olfactory Bulb Structure where synapses
form between the terminals of the olfactory nerve and the dendrites of
mitral, periglomerular, and tufted cells? Glomeruli
The Smell Sensation Pathway is unique among the human senses because its
sensory information is the only one that: Bypasses the thalamus and connects directly to the forebrain.
The medical condition characterized by a partial or complete loss of the
sense of smell is: Anosmia
Due to the unique pathway of the sense of smell, its initial processing is
directly connected to structures in the forebrain, bypassing the usual
sensory relay center known as the: Thalamus
The sense of taste is scientifically referred to as: Gustation
According to the provided , where are taste buds primarily concentrated on
the tongue? Along the sides of the tongue
The statement under Taste Bud Functionality suggests that one taste bud is
capable of: Detecting all five tastes.
The concept that Each taste bud contains specialized cells for each taste
refers to the intricate design of the: Taste Bud Structure
If a person suffers from the complete loss of the sense of smell, they are
said to have Anosmia. The consequence of this is often a severe loss of
which other sense? Gustation
An individual's large hands and tiny back are represented on the Sensory
Homunculus with corresponding large and small areas, respectively. This
difference in area size is determined by the body part's: Density of sensory receptors/Input
The Somatosensory Cortex is distinct from the motor cortex because its
primary function is to receive: All sensory input from the body.
When an individual drinks a very hot beverage, the feeling of heat is
primarily registered by the specialized sensory process known as: Thermoreception
