In anatomy and osteology, a foramen (/ f ə ˈ r eɪ m ən /; [1] [2] pl.: foramina, / f ə ˈ r æ m ɪ n ə / or foramens / f ə ˈ r eɪ m ən z /; from Latin ' an opening produced by boring ') is an opening or enclosed gap within the dense connective tissue (bones and deep fasciae) of extant and extinct amniote animals, typically to allow passage of nerves, arteries, veins or other soft ...
A foramen is any opening, particularly referring to those in bone. [14] Foramina inside the body of humans and other animals typically allow muscles, nerves, arteries, veins, or other structures to connect one part of the body with another. An example is the foramen magnum in occipital bone.
Apical foramen, the opening at the tip of the root of a tooth; Foramen ovale (heart), an opening between the venous and arterial sides of the fetal heart; Foramen transversarium, one of a pair of openings in each cervical vertebra, in which the vertebral artery travels; Greater sciatic foramen, a major foramen of the pelvis
The interventricular foramina are two holes (Latin: foramen, pl. foramina) that connect the left and the right lateral ventricles to the third ventricle. [1]They are located on the underside near the midline of the lateral ventricles, [2] and join the third ventricle where its roof meets its anterior surface. [3]
The nutrient canal (foramen) is directed away from the growing end of bone. The growing ends of bones in upper limb are upper end of humerus and lower ends of radius and ulna. In lower limb, the lower end of femur and upper end of tibia are the growing ends. [1] The nutrient arteries along with nutrient veins pass through this canal.
The foramen spinosum was first described by the Danish anatomist Jakob Benignus Winslow in the 18th century. It is so-named because of its relationship to the spinous process of the greater wing of the sphenoid bone. However, due to incorrectly declining the noun, the literal meaning is "hole full of thorns" (Latin: foramen spinosum).
In human anatomy, the omental foramen (epiploic foramen, foramen of Winslow after the anatomist Jacob B. Winslow, or uncommonly aditus; Latin: Foramen epiploicum) is the passage of communication, or foramen, between the greater sac, and the lesser sac of the peritoneal cavity.
The foramen rotundum is one of the several circular apertures (the foramina) located in the base of the skull, in the anterior and medial part of the sphenoid bone. The mean area of the foramina rotunda is not considerable, which may suggest that they play a minor role in the dynamics of blood circulation in the venous system of the head. [1]
