Anterior funiculus
Item #4
Gray's subject #185 753

The most lateral of the bundles of the anterior nerve roots is generally taken as a dividing line which separates the antero-lateral region into two parts, viz., an anterior funiculus, between the anterior median fissure and the most lateral of the anterior nerve roots; and a lateral funiculus, between the exit of these roots and the postero-lateral sulcus.

Spinal cord

epidural space, dura mater, subdural space, arachnoid mater, subarachnoid space, pia mater, denticulate ligaments, conus medullaris, cauda equina, filum terminale, cervical enlargement, lumbar enlargement, anterior median fissure, dorsal root, dorsal root ganglion, dorsal ramus, ventral root, ventral ramus, sympathetic trunk, gray ramus communicans, white ramus communicans The Spinal cord nested in the vertebral column. ... The epidural space is a part of the human spine which is very close to the spinal cord, lying just outside the dura mater. ... The dura mater (from the Latin hard mother), or pachymeninx, is the tough and inflexible outermost of the three layers of the meninges surrounding the brain. ... The Cavum Subdurale (subdural space) is an artificial space created by the separation of the arachnoid mater from the dura mater as the result of trauma or pathologic process. ... The Arachnoid mater is one of the three layers of the meninges, interposed between the dura mater and the pia mater and separated from the pia mater by the subarachnoid space. ... The meninges (singular meninx) are the system of membranes that contain the brain. ... The pia mater (Latin: tender mother, itself a translation from Arabic) is the delicate innermost layer of the meninges - the membranes surrounding the brain and spinal cord. ... The conus medullaris is the terminal end of the spinal cord. ... The cauda equina is a structure within the lower end of the spinal column, that consists of nerve roots and rootlets from above. ... The spinal cord is a part of the vertebrate nervous system that is enclosed in and protected by the vertebral column (it passes through the spinal canal). ... penis ... This is a dorsal root ganglion (DRG) from a chicken embryo (around stage of day 7) after incubation overnight in NGF growth medium stained with anti-neurofilament antibody. ... In anatomy and neurology, the ventral root is the efferent motor root of a spinal nerve. ...


grey matter: central canal, substantia gelatinosa of Rolando, reticular formation, substantia gelatinosa centralis, interneuron, anterior horn, lateral horn, posterior horn (column of Clarke, dorsal spinocerebellar tract) Grey matter is a major component of the central nervous system, consisting of nerve cell bodies and short nerve cell extensions/processes (axons and dendrites). ... Cross-section through cervical spinal cord. ... Reticular formation is a part of the brain which is involved in stereotypical actions, such as walking, sleeping, and lying down. ... An interneuron (also called relay neuron or association neuron) is a neuron that communicates only to other neurons. ... In the thoracic region, the postero-lateral part of the anterior column projects lateralward as a triangular field, which is named the lateral column (lateral cornu, lateral horn). ... The posterior horn of the spinal cord is dorsal(more towards the back) to the anterior horn. ... The dorsal spinocerebellar tract conveys proprioceptive information from the body to the cerebellum. ...


white matter: anterior funiculus: descending (anterior corticospinal tract, vestibulospinal fasciculus, tectospinal tract), ascending (anterior spinothalamic tract, anterior proper fasciculus) White matter is one of the two main solid components of the central nervous system. ... The anterior corticospinal tract (also called the direct pyramidal tract or anterior cerebrospinal fasciculus) is a small bundle of descending fibers that connect the cerebral cortex to the spinal cord. ... The tectospinal tract is part of the indirect extrapyramidal tract and is responsible for coordinating head and eye movements, It is responsible for impulses that are motor. ... The spinothalamic tract is the sensory pathway in the body that transmits pain, temperature, itch and crude touch. ...


lateral funiculus: descending (lateral corticospinal tract, rubrospinal tract, olivospinal tract), ascending dorsal spinocerebellar tract, ventral spinocerebellar tract, spinothalamic tract, lateral spinothalamic tract, anterior spinothalamic tract, spinotectal tract, posterolateral tract, lateral proper fasciculus, medial longitudinal fasciculus The corticospinal or pyramidal tract is a massive collection of axons that travel between the cerebral cortex of the brain and the spinal cord. ... The rubrospinal tract is part of the indirect extra-pyramidal tract and is responsible for large muscle movement such as the arms and the legs. ... The dorsal spinocerebellar tract conveys proprioceptive information from the body to the cerebellum. ... The ventral spinocerebellar tract conveys proprioceptive information from the body to the cerebellum. ... The spinothalamic tract is the sensory pathway in the body that transmits pain, temperature, itch and crude touch. ... The spinothalamic tract is the sensory pathway in the body that transmits pain, temperature, itch and crude touch. ... The spinothalamic tract is the sensory pathway in the body that transmits pain, temperature, itch and crude touch. ... The medial longitudinal fasciculus (MLF) is a group of axons on each side of the brainstem, that carry information about the direction that the eyes should move. ...


posterior funiculus: fasciculus gracilis, fasciculus cuneatus, posterior proper fasciculus

Throughout the cervical and thoracic regions the central canal is situated in the anterior third of the medulla spinalis; in the lumbar enlargement it is near the middle, and in the conus medullaris it approaches the posterior surface.
The anterior funiculus lies between the anterior median fissure and the most lateral of the anterior nerve roots: the lateral funiculus between these nerve roots and the postero-lateral sulcus; and the posterior funiculus between the postero-lateral and the posterior median sulci (Fig.
The tectospinal fasciculus, situated partly in the anterior and partly in the lateral funiculus, is mainly derived from the opposite superior colliculus of the mid-brain.

The trigonum olfactorium, anterior perforated substance and the adjoining part of the septum pellucidum are important primary olfactory centers, especially for olfactory reflexes; in these centers terminate many axons from the mitral cells of the olfactory bulb.
The majority of the axons that arise from the mitral cells of the olfactory bulb and course in the olfactory tract course in the lateral olfactory stria to the uncus and hippocampal gyrus, and terminate in the cortex.
The tænia semicircularis extends from the region of the anterior perforated substance to the nucleus amygdalæ.
