What is the foramen of a bone?
A foramen (plural: foramina ) is an opening inside the body that allows key structures to connect one part of the body to another. The skull bones that contain foramina include the frontal, ethmoid, sphenoid, maxilla, palatine, temporal, and occipital.
What is the purpose of foramen in bones?
Definition. A foramen (plural foramina ) is an opening or hole through tissue, usually bone. It allows nerves and blood vessels to travel from one side of the tissue layer to the other. Foramina are primarily found in the skull; others are located in the vertebrae, long bones, roots of the teeth, heart, and abdomen.
What is an example of foramen?
Foramen – A hole through which nerves and blood vessels pass. Examples include supraorbital foramen, infraorbital foramen, and mental foramen on the cranium. Examples include trochlear fossa, posterior, middle, and anterior cranial fossa.
Where is the foramen located?
The foramen magnum (Latin: great hole) is a large oval opening ( foramen ) in the occipital bone of the skull in humans and many other animals. It is one of the several oval or circular openings ( foramina ) in the base of the skull.

What is foramen Rotundum?
The foramen rotundum (plural: foramina rotunda) is located in the middle cranial fossa, inferomedial to the superior orbital fissure at the base of greater wing of the sphenoid bone. It transmits the maxillary branch of trigeminal nerve (V2), artery of foramen rotundum, and emissary veins.
What is the largest foramen in the human body?
The largest foramen in the body is the obturator foramen, which is in the pelvic bone.
Is foramen magnum part of the brain?
The foramen magnum functions as a passage of the central nervous system through the skull connecting the brain with the spinal cord. On either side of the foramen magnum is an occipital condyle.
What foramen means?
: a first or chief person: such as. a: a member of a jury who acts as chairman and spokesman. b(1): a chief and often specially trained worker who works with and usually leads a gang or crew. (2): a person in charge of a group of workers, a particular operation, or a section of a plant. 6
What nerve passes through foramen ovale?
The important structures which pass through it are the mandibular nerve, the accessory meningeal artery, the lesser superficial petrosal nerve and the emmissary vein . This is the one of the important foramina which are situated at the transition zone between the intracranial and the extracranial structures .
What is Stylomastoid foramen?
The stylomastoid foramen is a rounded opening at the inferior end of the facial canal. It is located on the inferior surface of the petrous temporal bone, between the base of the styloid process and the mastoid process of the temporal bone.
Is a fissure a depression or opening?

What is Infraorbital foramen?
The infraorbital foramen, an opening into the floor of the eye socket, is the forward end of a canal through which passes the infraorbital branch of the maxillary nerve, the second division of the fifth cranial nerve.
Where is the foramen magnum Located in humans?
The foramen magnum is situated in the occipital bone, and forms around the base of the brainstem (the medulla oblongata), separating the brain above from the spinal cord below.
What passes through Stylomastoid foramen?
The stylomastoid foramen is between the styloid and mastoid processes of the temporal bone. It is the termination of the facial canal, and transmits the facial nerve and stylomastoid artery.
Does food pass through the foramen magnum?
The foramen magnum allows nerves connecting the brain and spinal cord to pass through, whereas the esophagus allows food to pass from the mouth to the stomach.
