Question

Proprioceptive neurons innervate joints and tendons, providing information about the position of body parts. "The spinal cord extends from the foramen magnum of the skull to the second lumbar vertebra." Match these terms with the correct statement or definition: Gray matter in the spinal cord containing sensory neurons. Gray matter in the spinal cord containing motor neurons. Gray matter in the spinal cord containing sympathetic autonomic neurons. Part of white matter; ascending or descending axons that are grouped by function; nerve pathway. Afferent nerve processes that canny action potentials to the spinal cord. Efferent nerve processes that canny action potentials away from the spinal cord. Structures containing the cell bodies of afferent neurons. Formed by joining of dorsal and ventral roots.

Explanation / Answer

Dorsal root ganglia – Grey matter in the spinal cord containing sensory neurons.

Dorsal roots - Grey matter in the spinal cord containing motor neurons.

Nerve tract -   Part of white matter; ascending and descending axons that are grouped by function; nerve pathway.

Spinal nerve – Formed by joining dorsal and ventral root.

Anterior (Vertical) Horn – Afferent nerve processes that carry action potentials to the spinal cord

Posterior (dorsal) horn – Efferent nerve processes that carry action potentials away from the spinal cord.

Ventral Root - Structures containing the cell bodies of afferent neurons

Lateral Horn- Grey matter in the spinal cord containing sympathetic automatic neurons
