What is the site of sella turcica called?
Structure. The sella turcica is located in the sphenoid bone behind the chiasmatic groove and the tuberculum sellae. It belongs to the middle cranial fossa. The sella turcica’s most inferior portion is known as the hypophyseal fossa (the “seat of the saddle”), and contains the pituitary gland (hypophysis).
What is the posterior bones of the hard palate?
The Axial Skeleton
| A | B |
|---|---|
| Palatine | posterior bones of the hard palate |
| Parietal | much of the lateral and superior cranium |
| Sphenoid | single, irregular, bat-shaped bone forming part of the cranial floor |
| Lacrimal | tiny bones bearing tear ducts |
What is the foramen magnum contained here?
It is located in the most inferior portion of the cranial fossa as a part of the occipital bone. Its contents include the medulla oblongata, meninges, spinal root of cranial nerve XI, vertebral arteries, anterior and posterior spinal arteries, the tectorial membrane, and alar ligaments.
What tiny bones bear tear ducts?
Specifically, the lacrimal bone helps form the nasolacrimal canal necessary for tear translocation. A depression on the anterior inferior portion of the bone, the lacrimal fossa, houses the membranous lacrimal sac. Tears or lacrimal fluid, from the lacrimal glands, collect in this sac during excessive lacrimation.
Which bone is the strongest bone of the face?
mandible
Where is frontal bone located?
skull
Does the frontal bone contain a sinus?
The large facial bones that surround the nasal cavity – the frontal bone, the maxilla, the sphenoid and ethmoid bones – are hollow to a greater or lesser extent. The hollow spaces in these bones contain the paranasal sinuses, which in the healthy living body are filled with air.
Is the frontal bone strong?
In comparing the impact strength of three facial bones on each of four cadavers, the frontal bone has been found to tolerate a force three or four times higher than the mandible and zygomatic bone which are about equal.
What body part does the frontal bone form?
forehead
Which bones make up forehead?
The frontal bone forms the forehead. The two parietal bones form the upper sides of the skull; the two temporal bones form the lower sides. The butterfly-shaped sphenoid bone is located at the base of the skull.
Which part of the skull is the strongest?
Some strength tests show the temporal bone in the skull to be the strongest bone. CONCLUSION: The thickest area of the skull is the parasagittal posterior parietal area in male skulls and the posterior parietal area midway between the sagittal and superior temporal line in female skulls.
Which part of brain is most sensitive?
The Prefrontal Cortex Is the Most Sensitive Place in the Frontal Lobe. Within the frontal lobe, the most susceptible area to injury lies at the very front of the brain behind the skull.
What is the softest part of your skull?
Clinical significance. The pterion is known as the weakest part of the skull. The anterior division of the middle meningeal artery runs underneath the pterion.
