The connections between the terminal nerve and the olfactory system have been extensively studied in human embryos. olfactory nerve fibers enter the brain at stage 17, fibers from the vomeronasal organ and fibers of the terminal nerve enter the brain at stages 17 and 18. [9] During prenatal development some of the ganglion cells are lost. [7]
The ciliospinal center (also known as Budge's center [1]) is a cluster of [citation needed] pre-ganglionic sympathetic neuron cell bodies located in the intermediolateral cell column (of the cornu laterale) at spinal cord segment (C8: Anatomic variation) T1-T2 [2]
Axon terminals (also called terminal boutons, synaptic boutons, end-feet, or presynaptic terminals) are distal terminations of the branches of an axon. An axon, also called a nerve fiber, is a long, slender projection of a nerve cell that conducts electrical impulses called action potentials away from the neuron's cell body to transmit those ...
The filum terminale is situated centrally [2] amid the spinal nerve roots of the cauda equina [3] [2] (but is not itself a part of the cauda equina [2]).. The inferior-most spinal nerve, the coccygeal nerve, leaves the spinal cord at the level of the conus medullaris via respective vertebrae through their intervertebral foramina, superior to the filum terminale.
The lamina terminalis is a thin layer that forms the median portion of the wall of the forebrain.It stretches from the interventricular foramen (foramen of Monro) to the recess at the base of the optic stalk (optic nerve) and contains the vascular organ of the lamina terminalis, which regulates the osmotic concentration of the blood.
The stria terminalis (or terminal stria) is a structure in the brain consisting of a band of fibers running along the lateral margin of the ventricular surface of the thalamus. Serving as a major output pathway of the amygdala , the stria terminalis runs from its centromedial division to the ventromedial nucleus of the hypothalamus .
The sympathetic trunk is a fundamental part of the sympathetic nervous system, and part of the autonomic nervous system.It allows nerve fibres to travel to spinal nerves that are superior and inferior to the one in which they originated.
The intermediolateral nucleus (IML) is located in Rexed lamina VII of the lateral grey column, one of three grey matter columns found in the spinal cord. The intermediolateral cell column exists at vertebral levels T1 – L3. [1] It mediates the entire sympathetic innervation of the body, but the nucleus resides in the grey matter of the spinal ...
