Which bones contain a fossa?
The middle cranial fossa consists of three bones – the sphenoid bone and the two temporal bones..
What is foramen Rotundum?
Foramen Rotundum. The foramen rotundum is located at the base of the greater wing of the sphenoid, inferior to the superior orbital fissure. It provides a connection between the middle cranial fossa and the pterygopalatine fossa. The maxillary nerve (branch of the trigeminal nerve, CN V) passes through this foramen.
What are the 3 cranial fossa?
The Anterior Cranial Fossa. The floor of the cranial cavity is divided into three distinct depressions. They are known as the anterior cranial fossa, middle cranial fossa and posterior cranial fossa. Each fossa accommodates a different part of the brain.
What does the foramen Rotundum transmit?
Function. The foramen rotundum allows the passage of the maxillary nerve (V2), a branch of the trigeminal nerve. It also allows the passage of the artery of the foramen rotundum and an emissary vein.

What does the mandibular fossa do?
The mandibular fossa is the cavity in the temporal bone that enables interaction with the mandibular condyle. The mandibular fossa of the temporal bone borders with articular tubercle in the front and is separated from the external acoustic meatus by the tympanic part of the bone on the backside.
What is the function of the hypophyseal fossa?
The optic canal connecting the middle cranial fossa to the orbit transmits the optic nerve and the ophthalmic artery. In the middle of the middle cranial fossa is the pituitary fossa or sella turcica (hypophyseal fossa) containing the pituitary gland.
Which is the largest foramen in the human body?
The largest foramen in the body is the obturator foramen, which is in the pelvic bone.
How big is a fossa?
What nerve passes through the Stylomastoid foramen?
The facial nerve then exits the facial canal (and the cranium) via the stylomastoid foramen. This is an exit located just posterior to the styloid process of the temporal bone.
What is the largest foramen in the body what is its function?
The largest foramen in the human skeleton is the obturator foramen in the pelvic bone. … The foramen, which means hole, allows a path out of the torso for the nerves and blood vessels to the front of the legs.
What bone supports the tongue?
Hyoid boneHyoid bone, U-shaped bone situated at the root of the tongue in the front of the neck and between the lower jaw and the largest cartilage of the larynx, or voice box. The primary function of the hyoid bone is to serve as an attachment structure for the tongue and for muscles in the floor of the oral cavity.
Where is the Pterygopalatine fossa?
The pterygopalatine fossa (PPF) is a small, clinically inaccessible, fat-filled space located in the deep face that serves as a major neurovascular crossroad between the oral cavity, nasal cavity, nasopharynx, orbit, masticator space, and the middle cranial fossa.
Is foramen and fossa the same thing?
Foramen – A hole through which nerves and blood vessels pass. Examples include supraorbital foramen, infraorbital foramen, and mental foramen on the cranium. Fossa – A shallow depression in the bone surface.
What is meant by fossa?
In anatomy, a fossa (/ˈfɒsə/; plural fossae (/ˈfɒsiː/ or /ˈfɒsaɪ/); from the Latin “fossa”, ditch or trench) is a depression or hollow, usually in a bone, such as the hypophyseal fossa (the depression in the sphenoid bone). Some examples include: In the Skull: Cranial fossa. Anterior cranial fossa.
Where is the fossa in the body?
The fossa is located behind the zygomatic process of the frontal bone in the anterior and lateral part of the orbital roof.
What is the head called in anatomy?
Alternative Title: cephalon. Head, in human anatomy, the upper portion of the body, consisting of the skull with its coverings and contents, including the lower jaw.
Which bone is the longest bone in the human body?
femurThe femur is one of the most researched bones in the human anatomy and forensic medicine. As the longest bone in the human body, it is well preserved in skeletal remains.
