  2. Spinothalamic tract - Wikipedia

    en.wikipedia.org/wiki/Spinothalamic_tract

    The spinothalamic tract is a nerve tract in the anterolateral system in the spinal cord. [1] This tract is an ascending sensory pathway to the thalamus.From the ventral posterolateral nucleus in the thalamus, sensory information is relayed upward to the somatosensory cortex of the postcentral gyrus.

  3. Medial lemniscus - Wikipedia

    en.wikipedia.org/wiki/Medial_lemniscus

    The medial lemniscus carries axons from most of the body and terminates by synapsing with third-order neurons in the ventral posterolateral nucleus of the thalamus. [3] at the level of the mamillary bodies. Sensory axons transmitting information from the head and neck via the trigeminal nerve synapse at the ventral posteromedial nucleus of the ...

  4. Neural pathway - Wikipedia

    en.wikipedia.org/wiki/Neural_pathway

    In neuroanatomy, a neural pathway is the connection formed by axons that project from neurons to make synapses onto neurons in another location, to enable neurotransmission (the sending of a signal from one region of the nervous system to another). Neurons are connected by a single axon, or by a bundle of axons known as a nerve tract, or ...

  5. Anterior white commissure - Wikipedia

    en.wikipedia.org/wiki/Anterior_white_commissure

    Two of the five sensory modalities, pain and temperature, cross sides at the anterior white commissure, reaching the contralateral side about two vertebral levels rostral to their origin. The spinothalamic tract thus decussates very soon after entering the spinal cord, ascending in the spinal cord, contralateral to the side from where it ...

  7. Ventral trigeminal tract - Wikipedia

    en.wikipedia.org/wiki/Ventral_trigeminal_tract

    The ventral trigeminal tract, ventral trigeminothalamic tract, anterior trigeminal tract, or anterior trigeminothalamic tract, is a tract composed of second-order neuronal axons. These afferent fibers carry sensory information about discriminative and crude touch, conscious proprioception, pain, and temperature from the head, face, and oral cavity.

  8. Nerve tract - Wikipedia

    en.wikipedia.org/wiki/Nerve_tract

    A nerve tract is a bundle of nerve fibers connecting nuclei of the central nervous system. [1] [2] [3] In the peripheral nervous system, this is known as a nerve fascicle, and has associated connective tissue. The main nerve tracts in the central nervous system are of three types: association fibers, commissural fibers, and projection fibers.

  9. Extrapyramidal system - Wikipedia

    en.wikipedia.org/wiki/Extrapyramidal_system

    The pyramidal tracts (corticospinal tract and corticobulbar tracts) may directly innervate motor neurons of the spinal cord or brainstem (anterior (ventral) horn cells or certain cranial nerve nuclei), whereas the extrapyramidal system centers on the modulation and regulation (indirect control) of anterior (ventral) horn cells.
