What is temporal fossa content?
The temporal fossa is primarily occupied by the temporalis muscle, but there are a few other contents which include: deep temporal arteries. deep temporal nerves. superficial temporal artery.
What is temporal and infratemporal fossa?
Temporal fossa. Fossa temporalis. The infratemporal fossa is a space below the temporal fossa. A view of the skull without the soft tissues shows that these two anatomical structures communicate with one another. The fossa is irregularly shaped and is situated below and medial to the zygomatic arch.
What muscle attaches to the temporal fossa?
Temporalis muscle
| Temporalis muscle | |
|---|---|
| Insertion | coronoid process of the mandible and retromolar fossa |
| Artery | deep temporal arteries |
| Nerve | deep temporal nerves, branches of the anterior division of the mandibular nerve (V3) |
| Actions | elevation and retraction of mandible |
What is a temporal line?
Medical Definition of temporal line : either of two nearly parallel ridges or lines on each side of the skull that begin as a single ridge on the temporal bone, run upward and backward from the zygomatic process above the temporal fossa, divide into upper and lower lines, and continue on the parietal bone.
What is fossa structure?
The posterior cranial fossa is part of the cranial cavity, located between the foramen magnum and tentorium cerebelli. It contains the brainstem and cerebellum. This is the most inferior of the fossae. It houses the cerebellum, medulla and pons. Anteriorly it extends to the apex of the petrous temporal.
What is temporal fossa in reptiles?
The reptiles are classified mainly on the structure of their skulls, in which there are temporal vacuities or fossae or empty spaces in the temporal region. The function of these temporal fossae was probably to enable the jaw muscles to protrude out onto the upper surface of the skull.
What is the function of temporal fossa?
The temporal fossa serves as a site of origin for the temporal muscle. It originates from the superior, anterior and posterior borders of the temporal fossa and resides within its concavity as the muscle fibers move towards their insertion point, which lies under the zygomatic arch.
What is the temporal process?
Medical Definition of temporal process : a process of the zygomatic bone that with the zygomatic process of the temporal bone with which it articulates laterally forms part of the zygomatic arch.
What is the function of the temporal lines?
Temporal muscle
| Origin | Temporal fossa (up to inferior temporal line), Temporal fascia |
|---|---|
| Insertion | Apex and medial surface of coronoid process of mandible |
| Action | Anterior fibres: Elevates mandible Posterior part: Retracts mandible |
| Innervation | Deep temporal branches (of mandibular nerve (CN V3)) |
Where is a 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 meaning of Hauser?

What is the temporal fossa in the skull?
The Temporal Fossa. The temporal fossa is a depression on the temporal region and one of the largest landmarks on the skull. The temporal bone, the sphenoid bone, the parietal bone and the frontal bone contribute to its concave wall. It is superior to the infratemporal fossa which lies beneath the zygomatic arch. Contents.
What is the origin of the temporal muscle?
It originates from the superior, anterior and posterior borders of the temporal fossa and resides within its concavity as the muscle fibers move towards their insertion point, which lies under the zygomatic arch. Temporal muscle covering the contents of the temporal fossa.
Which bones make up the concave wall of the temporal bone?
The temporal bone, the sphenoid bone, the parietal bone and the frontal bone contribute to its concave wall. It is superior to the infratemporal fossa which lies beneath the zygomatic arch.
What is the border of the temporal bone?
Borders Both superiorly and posteriorly the temporal fossa is bordered by the superior temporal line (origin of the deep temporal fascia). The inferior border runs along the zygomatic arch. Lastly, the anterior border is marked by the frontal process of the zygoma and the zygomatic process of the frontal bone.
