The dorsal (from Latin dorsum, meaning ‘back’) surface of an organism refers to the back, or upper side, of an organism. If talking about the skull, the dorsal side is the top. For example, in a fish the pectoral fins are dorsal to the anal fin, but ventral to the dorsal fin.

Medical Definition of Dorsal Dorsal: Relating to the back or posterior of a structure. As opposed to the ventral, or front, of the structure. Some of the dorsal surfaces of the body are the back, buttocks, calves, and the knuckle side of the hand.

Furthermore, what is meant by ventral side?

ventral. The adjective ventral refers to the area on the body in the lower front, around the stomach area. The ventral fin on a fish is the one on its belly. In directional terms, the ventral side is the area forward from (or under) the spinal cord.

Is dorsal and posterior the same?

Anterior (or ventral) Describes the front or direction toward the front of the body. The toes are anterior to the foot. Posterior (or dorsal) Describes the back or direction toward the back of the body.

What is the opposite of dorsal?

“Dorsal” can be used of non-living things too (in particular, the backs of airplanes), as can its opposite, “ventral,” which means “relating to the belly.” “Dorsal” descends from Latin “dorsum” (“back”), which also gave us “dossier” (via French, for a bundle of documents labeled on the back) and “reredos” (“an

Do humans have a dorsal?

Dorsal (from Latin dorsum meaning “back”) refers to the body region/”side” opposite that of ventral (and typically called the “back”). Sometimes anterior/posterior would be synonymous with ventral/dorsal, as is the case in humans or other bipedal organisms.

What is the dorsal part of the body?

Anterior or ventral – front (example, the kneecap is located on the anterior side of the leg). Posterior or dorsal – back (example, the shoulder blades are located on the posterior side of the body). Medial – toward the midline of the body (example, the middle toe is located at the medial side of the foot).

Where is the dorsal part of the body?

The dorsal body cavity is located along the dorsal (posterior) surface of the human body, where it is subdivided into the cranial cavity housing the brain and the spinal cavity housing the spinal cord.

What does dorsal mean in biology?

Definition. adjective. (1) (anatomy) Of, toward, in, on, or near the back (or any analogous bodily reference) of an organism. (2) (zoology) Of, or pertaining to, the dorsum. (3) (botany) Of or on the surface away from the axis; abaxial.

What is the root of the word dorsal?

dorsal (adj.) in anatomy, “of or pertaining to the back,” late 14c., from Old French dorsal (14c.) or directly from Medieval Latin dorsalis, corresponding to Latin dorsualis “of the back,” from dorsum “back,” which is of uncertain origin. Related: Dorsally.

What is sagittal view?

Sagittal: A vertical plane passing through the standing body from front to back. The mid-sagital, or median, plane splits the body into left and right halves. For a more complete listing of terms used in medicine for spatial orientation, please see the entry to “Anatomic Orientation Terms”.

What does the dorsal cavity contain?

dorsal cavity: The cavity in the back of the body that contains the cranial and vertebral cavities, which house the brain and spinal cord respectively.

What is the opposite of ventral?

Ventral is an adjective with the meanings: Directed toward or situated on the belly surface of, or anterior aspect of, the body; pertaining to the part or location opposite the anatomic back. The opposite of ventral is dorsal.

What is another word for ventral?

ventral(adj) toward or on or near the belly (front of a primate or lower surface of a lower animal) “the ventral aspect of the human body”; “the liver is somewhat ventral in position”; “ventral (or pelvic) fins correspond to the hind limbs of a quadruped” Synonyms: adaxial.

What is the difference between dorsal and ventral?

Ventral means ‘towards the stomach’. In humans, it’s towards the front (and generally means the same thing as ‘anterior’). In some other animals, such as dogs, cats and horses, it would mean towards the ground, because that’s where their stomachs point. Dorsal is the opposite, and means ‘towards the back’.

Why is anatomical position important?

The anatomical position is of importance in anatomy because it is the position of reference for anatomical nomenclature. Anatomic terms such as anterior and posterior, medial and lateral, abduction and adduction, and so on apply to the body when it is in the anatomical position.

What are the different anatomical terms?

In general, directional terms are grouped in pairs of opposites based on the standard anatomical position. Superior and Inferior. Superior means above, inferior means below. Anterior and Posterior. Medial and Lateral. Proximal and Distal. Superficial and Deep.

What is posteriorly?

adjective. situated behind or at the rear of; hinder (opposed to anterior). coming after in order, as in a series. coming after in time; later; subsequent (sometimes followed by to).
