Anterior cranial fossa which accommodates the anterior lobe of brain.
Middle cranial fossa, much wider than the anterior cranial fossa contain the 2 temporal lobes of brain.
Posterior cranial fossa is much shallower and wider than the middle cranial fossa and it accommodates the occipital lobes of the brain.
There are three cranial fossae, each housing different lobes of the brain.
* Anterior cranial fossa - houses the frontal lobes * Middle cranial fossa - houses the temporal lobes * Posterior cranial fossa - houses the occipital lobes, as well as the cerebellum and medulla

What are 4 bones containing paranasal sinuses?
The frontal bone, ethmoid bone, sphenoid bone, and maxillary bone contain paranasal sinuses. These sinuses are air-filled cavities within these bones that help to lighten the skull and produce mucus that helps humidify and filter the air we breathe.
What is the cranial floor?
The cranial floor is the bottom part of the skull that separates the cranial cavity from the facial structures. It consists of several bones, including the sphenoid, ethmoid, and occipital bones. The cranial floor also plays a crucial role in protecting the brain and supporting the structures of the face.
Why don't are ears have bones?
Ears do contain bones - the smallest bones in the human body, called the ossicles, are found in the middle ear. These bones (the malleus, incus, and stapes) are essential for transmitting sound vibrations from the eardrum to the inner ear. The outer and inner parts of the ear do not contain bones but comprise cartilage and soft tissues to support their structure and function.
What cranial nerve conducts sensory impulse from teeth and face?
The trigeminal nerve (cranial nerve V) conducts sensory impulses from the teeth and face. It is the largest cranial nerve and has three main branches (ophthalmic, maxillary, and mandibular) that innervate different regions of the face.
Which of the three meningeal layers forms the dural venous sinuses?
The dura mater forms the dural venous sinuses, which are venous channels located between the layers of the dura mater in the brain. These sinuses are important structures for draining blood and cerebrospinal fluid from the brain.

The protects the delicate tissues of the brain?
There are three things that protect the delicate tissue of the brain. The three things are bones of the cranium, the cranial meninges, and cerebrospinal fluid.

There are three things that protect the delicate tissue of the brain. The three things are bones of the cranium, the cranial meninges, and cerebrospinal fluid.
Which Body part does not have bones?
The ears do not have bones - that is, the external structures on the sides of our heads. There are three tiny bones in each of our 'inner ears', but the outside structure is made out of cartilage, not bone.
What cranial nerve covers meninges?
The Optic Nerve (one of the Cranial Nerves) is enclosed by three sheaths that are continuous with the three layers of cranial meninges (dura, arachnoid, and pia). The central artery and vein of the retina pass through these meningeal sheaths and are included in the distal part of the optic nerve.
Is mydriasis parasympathetic or sympathetic?
the parasympathetic fibers of the cranial nerve number three.
What nerves are involved in diplopia?
The cranial nerves involved in diplopia are the third (oculomotor), fourth (trochlear), and sixth (abducens) cranial nerves, which control eye movement and coordination. Issues with these nerves can result in misalignment of the eyes, leading to double vision.
What three cranial nerves are involved in the cardinal positions of gaze?
vagus, glossopharyngeal and facial
What three bones never grow?

How many bones in your arm?
