For the portion of the brain sometimes called the dorsal, see Medial longitudinal fasciculus.

Dorsal view of a rove beetle

In anatomy, the dorsum is the upper side of animals that typically run, fly, swim or crawl in a horizontal position, and the back side of animals (like humans) that walk upright. In vertebrates the dorsum contains the backbone. The term dorsal refers to anatomical structures that are either situated toward or grow off that side of an animal. The opposite side of the animal is described with the terms ventrum and ventral.

In lepidoptera (moths and butterflies), the dorsum also refers to the trailing edge of the wing (the leading edge is called the costa).

The term "dorsum" is used for the upper surface of the body of nudibranch sea slugs.

Human anatomy

In general, dorsal in terms of human anatomy is generally synonymous with posterior. For example, the heart is dorsal to the breastbone while the spinal column is dorsal to the heart.

Some exceptions exist, however due to varied orientation on quadrupedal mammals, where the term is more appropriately used. Examples of these include the back-side of the hand, the top-side of the foot and the upper surface of the tongue are referred to by the term dorsum.

In neurobiology, nerve rootlets stemming from the spinal cord form dorsal (sensory) and ventral (motor) roots before these unite to form the spinal nerve.

• Terminal distribution of the corticospinal projection from the hand/arm region of the primary motor cortex to the cervical enlargement in rhesus monkey.

• Morecraft RJ, Ge J, Stilwell-Morecraft KS, McNeal DW, Pizzimenti MA, Darling WG.Author information Division of Basic Biomedical Sciences, Laboratory of Neurological Sciences, University of South Dakota, Sanford School of Medicine, Vermillion, South Dakota, 57069.AbstractTo further our understanding of the corticospinal projection (CSP) from the hand/arm representation of the primary motor cortex (M1), high-resolution anterograde tracing methodology and stereology were used to investigate the terminal distribution of this connection at spinal levels C5 to T1. The highest number of labeled terminal boutons occurred contralaterally (98%) with few ipsilaterally (2%). Contralaterally, labeled boutons were located within laminae I-X, with the densest distribution found in lamina VII and, to a lesser extent, laminae IX and VI. Fewer terminals were found in other contralateral laminae. Within lamina VII, terminal boutons were most prominent in the dorsomedial, dorsolateral, and ventrolateral subsectors. Within lamina IX, the heaviest terminal labeling was distributed dorsally. Ipsilaterally, boutons were found in laminae V-X. The most pronounced distribution occurred in the dorsomedial and ventromedial sectors of lamina VII and fewer labeled boutons were located in other ipsilateral laminae. Segmentally, contralateral lamina VII labeling was highest at levels C5-C7. In contrast, lamina IX labeling was highest at C7-T1 and more widely dispersed among the quadrants at C8-T1. Our findings suggest dominant contralateral influence of the M1 hand/arm CSP, a contralateral innervation pattern in lamina VII supporting Kuypers (1982) conceptual framework of a "lateral motor system," and a projection to lamina IX indicating significant influence on motoneurons innervating flexors acting on the shoulder and elbow rostrally (C5-C7), along with flexors, extensors, abductors and adductors acting on the digits, hand and wrist caudally (C8-T1).

The purpose of our study was to determine if a targeted teaching session to the same group of junior doctors led to objective improvement in fracture reduction and plaster moulding and hence a decrease in the re-displacement of these fractures.

Electronic address: jcashom@upo.es.AbstractSegmented organisms have serially repeated structures [1] that become specialized in some segments [2]. We show here that the Drosophila corpora allata, prothoracic glands, and trachea have a homologous origin and can convert into each other. The tracheal epithelial tubes develop from ten trunk placodes [3, 4], and homologous ectodermal cells in the maxilla and labium form the corpora allata and the prothoracic glands. The early endocrine and trachea gene networks are similar, with STAT and Hox genes inducing their activation. The initial invagination of the trachea and the endocrine primordia is identical, but activation of Snail in the glands induces an epithelial-mesenchymal transition (EMT), after which the corpora allata and prothoracic gland primordia coalesce and migrate dorsally, joining the corpora cardiaca to form the ring gland. We propose that the arthropod ectodermal endocrine glands and respiratory organs arose through an extreme process of divergent evolution from a metameric repeated structure.
