Spinal nerve correct answers a mixed nerve, which carries motor, sensory, and autonomic signals
between the spinal cord and the body
dorsal root ganglion correct answers a cluster of cell bodies of first-order sensory neurons
located along a spinal nerve
Dorsal root correct answers he sensory branch of each spinal nerve, which consists of the central
processes of sensory neurons just prior to entering the spinal cord
Ventral root correct answers he motor branch of each spinal nerve, which consists of axons from
motor neurons whose cell bodies are found within the gray matter of the spinal cord
Primary somesthetic cortex correct answers located in the postcentral gyrus, the part of the
neocortex that processes tactile information.
Dorsal column correct answers medial lemniscus pathway - sensory pathways that extend from
the spinal cord to the thalamus and carry information about discriminative touch, pressure, and
proprioception information from the body
Spinothalamic tracts correct answers sensory pathways that extends from the spinal cord to the
thalamus and carry information about nondiscriminatory touch, pain, and temperature from the
body
Tegmentum correct answers the core part of the brainstem that is a continuation (has structures
continuous with) the spinal cord
Nontegmental structures correct answers structures that are discontinuous and appended to the
brainstem's surface, including tectum, cerebral peduncles, the ventral pons, and the pyramids
Corticobulbar tract (also known as the corticonuclear tract) correct answers part of the pyramidal
system that begins in the motor cortex and terminates on motor neurons within brainstem motor
nuclei to control the muscles of the face, head and neck
Hypothalamus correct answers a region of the forebrain below the thalamus which coordinates
both the autonomic nervous system and the activity of the pituitary
Thalamus correct answers a region of the forebrain located just above the brain stem between the
cerebral cortex and the midbrain, which relays motor and sensory signals to the cerebral cortex
Association fibers correct answers axons that connect cortical areas within the same cerebral
hemisphere
Projection fibers correct answers efferent and afferent fibers uniting the cortex with the lower
parts of the brain and with the spinal cord and brainstem
, Commissural fibers correct answers axons that connect the two hemispheres of the brain
Basal ganglia correct answers a group of structures linked to the thalamus in the base of the brain
and involved in regulation and coordination of movement (action selection)
Amygdala correct answers a mass of gray matter inside each cerebral hemisphere, involved with
the experiencing of emotions (e.g., fear and anxiety) and emotional memory
Hippocampus correct answers subcortical structure of the limbic system that appears involved in
learning and consolidation of short-term to long-term memory
Limbic system correct answers a complex system of structures in the brain, concerned with
emotional regulation and memory
Transducer correct answers sense organs that change one form of energy into another form of
energy, like action potentials
Light touch or discriminative touch correct answers touch which allows identification of shape
and other characteristics of an object, and includes 2- point sense, stereognosis, and
graphesthesia
Nondiscriminative touch correct answers touch which allows for generalized perception of touch
without localization
Mechanoreceptors correct answers respond to various kinds of tactile stimulation (i.e., light
touch, pressure, vibration)
Free nerve endings correct answers unencapsulated receptors primarily for temperature and pain
Papillae correct answers small projections on the dorsal surface of the tongue where the majority
of a person's taste buds are located that distinguish the five tastes: sweet, sour, bitter, salty, and
umami
Retina correct answers a layer at the back of the eyeball containing cells that are sensitive to light
and that trigger nerve impulses that pass via the optic nerve to the brain, where a visual image is
formed
Optic tract correct answers collection of retinal ganglion cell axons traveling between the optic
chiasm and the lateral geniculate body of the thalamus
Olfactory nerve correct answers the first cranial nerve, composed of the central processes of
bipolar cells that pass out of the nasal cavity into the cranial cavity and synapse with glomeruli
neurons of the olfactory bulb
