Front Back
Neural structure that controls muscle tone and the rate; range and force of motor movements
Frontal Lobe-fxn
Part of the brain that functions as an UMN center and contains the UMNs of the corticospinal tract; rostral to cruciate sulcus
Occipital Lobe-fxn
Area where the lateral geniculate projects for visual acuity; between parietal lobe and transverse fissure
Parietal Lobe-fxn
Part of the brain that perceives and integrates tactile; pain and proprioception information from the body and head; behind cruciate sulcus
Structure that coordinates muscle tone and locomotor activity
Cerebellar hemispheres-fxn
Area that coordinates skilled motor movements
Vestibular part of the cerebellar cortex that contains Purkinje neurons that function in equilibrium and balance
Piriform Lobe -fxn
Part of the brain that contains the amygdala; distal part of the hippocampus; tail of the caudate nucleus and part of the olfactory cortex; conscious perception of smell
Temporal Lobe-fxn
Part of the brain that receives axons from the medial geniculate nucleus; lateral cortex
Crus Cerebri-fxn
Axons in the Mesencephalon that are being projected from the internal capsule of the neocortex
Portion of rostral brain stem that contains sensory nuclei and nuclei that control the endocrine system; hypothalamus
Mammillary body-fxn
Ventral caudal most part of thalamus that fxns in short term memory relay and limbic system behaviors
Part of the brainstem that functions in eye movements visual and auditory reflexes
Part of brainstem that contains CN VI-XII and vital respiratory and cardiaovascular centers
Optic Tracts-fxn
Axons from the optic chiasm that are projecting to the lateral geniculate; rostral colliculus and preoptic area
Ventral part of the metencephalon that contains part of the trigeminal nuclear complex
Axons to brainstem nuclei and spinal cord
Cingulate gyrus-fxn
Cortical neurons that function in the limbic system and memory relay from the diencephalon
Corpus callosum-fxn
Axons that project to the contralateral cerebral hemisphere for interhemisphere integration.
Bundle of axons that reciprocally connects the hippocampus with the hypothalamus.
Ventral part of the diencephalon that functions in limbic system behavior; autonomic system and endocrine system control
Lobule that functions with the vestibular system in control of equilibrium and balance
Primary fissure-fxn
Divides the cerebellum into rostral and caudal lobes
Rostral colliculus-fxn
Visual relay and reflex center of the mesencephalon; sight avoidance and attention
Rostral commissure-fxn
Axons that interconnect contralateral olfactory bulbs and forebrain
Brain stem structure that is the major relay of all information except smell to the cerebrum
Cerebellar Peduncles-fxn
Axons that run between the spinal cord and the cerebellum
Caudal Colliculus-fxn
Auditory relay neurons of the mesencephalon
Lateral Geniculate Nucleus-fxn
Thalamic visual neurons that relay visual information to the visual cortex; conscious vision
Medial Geniculate Nucleus-fxn
Thalamic auditory neurons that relay to the auditory cortex
Trapezoid body-fxn
Auditory axons that cross in the ventral bulge of the myelencephalon
Vestibular Trigone-fxn
Area where the vestibular nuclei are located
Caudate Nucleus-fxn
UMN area of the cerebrum that forms the lateral boundary of the lateral ventricle
Cortical gyrus that functions in the limbic system; short term memory and connects part of the rhinencephalon with the diencephalon and septal nuclei.
Internal capsule-fxn
Axons that connect the neocortex with the brain stem and spinal cord
Preoptic area-fxn
Neurons that function in reproductive behavior; LHRH synthesis and release; temperature control; the parasympathetic system and sleep
Lenticular nucleus-fxn
UMNs that integrate motor activity and receive input from the caudate nucleus and projects to pallidum
Rostral Lobe-fxn
Fine motor control of trunk; rostral part of vermis
Caudal Lobe-fxn
Fine motor control of limbs; caudal part of vermis plus both hemispheres
Lateral Olfactory Tract-fxn
axons from olfactory bulb to piriform lobe
Medial Olfactory Tract-fxn
Axons from olfactory bulb to diencephalon; visceral responses to smell such as drooling
