Behavioral Neuroscience Neuroanatomy Quiz 2 (Functions)

What is the function of the Anterior Corticospinal Tract?

Involved in the control of axial and proximal limb musculature

What is the function of the Corticospinal Tract

descending motor pathway by which upper motor neurons project to lower motor neurons

What is the function of the Cuneate Tract?

Comprised of dorsal root ganglion axons that convey mechanosensory information from the upper limbs, trunk, and neck

What is the function of the Diencephalon?

Caudal subdivision that gives rise to the thalamus and hypothalamus

What is the function of the Dorsal Column-medial lemniscus?

somatic sensory pathway that conveys tactile and proprioceptive information for the body and posterior third of the head

What is the function of the Dorsal Columns?

White matter region between dorsal horns of the spinal cord

What is the function of the Dorsal Horn?

Dorsal (sensory) portion of the spinal cord gray matter

What is the function of the Dorsal Root Ganglia?

Segmental sensory ganglia of the spinal cord

What is the function of the Dorsal Roots?

Bundle of axons from root ganglia to horn carrying sensory information from the periphery

What is the function of the Dorsal Spinocerebellar Tract?

Ascending sensory tract that conveys proprioceptive information from the lower body

What is the function of the Forebrain?

Derived from prosencephalon

commonly used to denote cerebral hemispheres and diencephalon

What is the function of the Gracile Tract?

comprising the central processes of dorsal root ganglion axons that convey mechanosensory information from the lower body

What is the function of the Lateral Columns?

White matter in the lateral portion of the spinal cord bounded by the dorsal and ventral nerve roots and the gray matter

What is the function of the Lateral Corticospinal Tract?

Decussating component of the corticospinal projection that originates in the motor cortical areas

Governs the lower motor neuronal pools that control the distal extremities

What is the function of the Lateral Horn?

Prominent feature of the lateral aspect of the gray matter in thoracic segments of the spinal cord

Contains the intermediolateral cell column

What is the function of the Mesencephalon?

One of 3 primary vesicles of the developing neural tube that gives rise to the midbrain in the adult nervous system

What is the function of the Metencephalon?

Anterior subdivision of the hindbrain embryonic vesicle that gives rise to the pons and cerebellum in the adult nervous system

What is the function of the Midbrain?

Rostral portion of the brainstem bordered caudally by the pons and rostrally by the diencephalon

What is the function of the Myelencephalon?

Posterior subdivision of the hindbrain embryonic vesicle that gives rise to the medulla in the adult nervous system

What is the function of the Posterior Intermediate Sulcus?

Furrow in the paramedian dorsal column of the spinal cord

Marks the division between the gracile and cuneate tracts

What is the function of the Posterior Median Fissure?

Prominent furrow along the dorsal midline of the spinal cord that divides the gracile tracts on two sides

What is the function of the Prosencephalon?

Most rostral of the 3 primary vesicles that gives rise to the forebrain in the adult nervous system

What is the function of the Rhombencephalon?

Most caudal of the 3 primary vesicles of the developing neural tube that gives rise to the hindbrain

What is the function of the Spinal Cord?

Caudal division of the central nervous system below the brainstem involved in the governance of movements and the processing of sensations from the body below the head

What is the function of the Spinothalamic Tract?

White matter pathway in the anterior-lateral part of the spinal cord and lateral tegmentum of the brainstem

Major component of the anterolateral system which also contains axons that terminate in the brainstem

What is the function of the Telencephalon?

Region of the brain derived from the anterior aspect of the embryonic forebrain vesicle

Cerebral hemispheres, basal ganglia, and basal forebrain nuclei are derivatives of here

What is the function of the Ventral Corticospinal Tract?

Non-decussating component of the corticospinal projection that originates in the posterior frontal lobe

involved in the control of axial and proximal limb musculature

What is the function of the Ventral Horn?

Ventral portion of the spinal cord grey matter

Contains primary motor neurons which innervate skeletal muscle

What is the function of the Ventral Horn Motor Neurons?

Columns of lower motor neurons in the ventral horn of the spinal cord that govern the activities of the skeletal muscles in the body below the head

What is the function of the Ventral Spinocerebellar Tract?

Ascending sensory tract of the spinal cord that conveys information from the lower body
