Posterior Horn (other)
The term posterior horn (also dorsal horn, posterior cornu, dorsal cornu) may refer to: *Posterior horn of lateral ventricle in the brain, which passes forward, laterally and slightly downward, from the corpus callosum into the occipital lobe *Posterior horn of spinal cord The posterior grey column (posterior cornu, dorsal horn, spinal dorsal horn, posterior horn, sensory horn) of the spinal cord is one of the three grey columns of the spinal cord. It receives several types of sensory information from the body, inc ..., the dorsal (towards the back) grey matter section of the spinal cord that receives several types of sensory information from the body including light touch, proprioception, and vibration *Posterior horn of the thyroid (or, Zuckerkandl's tubercle), a pyramidal extension of the thyroid gland See also * Anterior horn (other) {{disambig ...

Posterior Horn Of Lateral Ventricle
The lateral ventricles are the two largest ventricles of the brain and contain cerebrospinal fluid (CSF). Each cerebral hemisphere contains a lateral ventricle, known as the left or right ventricle, respectively. Each lateral ventricle resembles a C-shaped cavity that begins at an inferior horn in the temporal lobe, travels through a body in the parietal lobe and frontal lobe, and ultimately terminates at the interventricular foramina where each lateral ventricle connects to the single, central third ventricle. Along the path, a posterior horn extends backward into the occipital lobe, and an anterior horn extends farther into the frontal lobe. Structure Each lateral ventricle takes the form of an elongated curve, with an additional anterior-facing continuation emerging inferiorly from a point near the posterior end of the curve; the junction is known as the ''trigone of the lateral ventricle''. The centre of the superior curve is referred to as the ''body'', while the three ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Posterior Horn Of Spinal Cord
The posterior grey column (posterior cornu, dorsal horn, spinal dorsal horn, posterior horn, sensory horn) of the spinal cord is one of the three grey columns of the spinal cord. It receives several types of sensory information from the body, including fine touch, proprioception, and vibration. This information is sent from receptors of the skin, bones, and joints through sensory neurons whose cell bodies lie in the dorsal root ganglion. Anatomy The posterior grey column is subdivided into six layers termed Rexed laminae I-VI *Marginal nucleus of spinal cord (lamina I) *Substantia gelatinosa of Rolando (lamina II) *Nucleus proprius (laminae III, IV) *Spinal lamina V, the neck of the posterior horn *Spinal lamina VI, the base of the posterior horn. The other four Rexed laminae are located in the other two grey columns in the spinal cord.

Zuckerkandl's Tubercle (thyroid Gland)
Zuckerkandl's tubercle is a pyramidal extension of the thyroid gland, present at the most posterior side of each lobe. Emil Zuckerkandl described it in 1902 as the ''processus posterior glandulae thyreoideae''.Zuckerkandl, E. (1902). Die Epithelkörperchen von Didelphys azara nebst Bemerkungen über die Epithelkörperchen des Menschen. ''Anatomische Hefte, 19''(1), 59-84. Although the structure is named after Zuckerkandl, it was discovered first by Otto Madelung in 1867 as the ''posterior horn of the thyroid''. The structure is important in thyroid surgery as it is closely related to the recurrent laryngeal nerve, the inferior thyroid artery The inferior thyroid artery is an artery in the neck. It arises from the thyrocervical trunk and passes upward, in front of the vertebral artery and longus colli muscle. It then turns medially behind the carotid sheath and its contents, and als ..., Berry's ligament and the parathyroid glands. The structure is subject to an important a ...
