What does the thalamus control

Back 7

integrate and relay sensory info from the face, retina, cochlea and taste receptors, interprets sensation of touch pain and temp

constricted pupils
lowers hr and respiratory rate
increased peristalsis
ACH secreted
decreases BP
relaxation of skin and ab arterioles

Descending tracts

Back 25

vestiblospinal

Front 26

vestibulospinal

Back 26

originates lateral vestibular nucleus, which lies in the floor of the fourth ventricle,
descend the length of the spinal cord in the ventral and lateral funiculi without crossing, enter laminae VIII and IX of the anterior horn, and end upon both alpha and gamma motor neurons, which innervate ordinary muscle fibres and fibres of the muscle spindle

Front 27

Corticospinal

Back 27

The Corticospinal Tract is the largest descending pathway in man. It originates in part from the pyramidal cells in the cortex of each cerebral hemisphere and courses through the internal capsule, then through the medullary pyramids. At this point some 80% of the fibres from each hemisphere, decussate in the pyramidal decussation, and continue to descend in the lateral white column of the opposite side. The remaining 20% continue down ipsilaterally, in the ventro-medial white column, to innervate bilaterally, the more medially located motor neurones of the axial and proximal muscles.

The crossed fibres in the lateral white columns comprise both sensory axons (from post-central gyrus and parietal association areas), and motor axons (from precentral gyrus and prefrontal areas). The sensory axons project into the dorsal horn of the grey matter, to effect feedback regulation of the input pathways. The motor axons terminate on motor neurones of the distal muscles, either directly, or indirectly via interneurones.
