What bone is the site of cribriform plate?
The cribriform plate (Latin “cribriform” = perforated) lies within the ethmoidal notch of the frontal bone and forms the roof of the nasal cavity. As the name suggests it comprises numerous openings through which the olfactory fibers from the nasal cavity pass through to the anterior cranial fossa.
What is the site of sella turcica?
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 bone is the site of styloid process?
The styloid process is a slender pointed piece of bone just below the ear. It projects down and forward from the inferior surface of the temporal bone, and serves as an anchor point for several muscles associated with the tongue and larynx.
What lies on the cribriform plate?
The olfactory bulb lies on the cribriform plate of the ethmoid bone on the ventral surface of the frontal lobe (Simpson & Sweazey, 2013).
Is the cribriform plate part of the ethmoid bone?
In mammalian anatomy, the cribriform plate, horizontal lamina or lamina cribrosa is part of the ethmoid bone. It is received into the ethmoidal notch of the frontal bone and roofs in the nasal cavities.
Is the cribriform plate part of the vomer?
The posterior border articulates by its upper half with the sphenoidal crest, by its lower with the vomer. The inferior border is thicker than the posterior, and serves for the attachment of the septal nasal cartilage of the nose….

Where is the sella located?
pituitary gland
The sella turcica is a saddle-shaped depression located in the bone at the base of skull (sphenoid bone), in which resides the pituitary gland.
Where is the sella turcica sphenoid?
The sella turcica is a bony depression in the sphenoid bone. The sella is bordered laterally by the cavernous sinuses, superiorly by the diaphragma sella (dural fold), anteroinferiorly by the sphenoid sinus and posteriorly by the pontine cistern. The pituitary gland normally sits within the sella.
What is the Stylohyoid attached to?
Stylohyoid is a paired muscle located in the anterior triangle of the neck. It is part of the suprahyoid muscle group which connects the hyoid bone to the mandible and skull….Stylohyoid muscle.

What is attached to styloid process?
The styloid process projects from the inferior part of the petrous temporal bone and offers attachment to the stylohyoid ligament and the stylohyoid, stylopharyngeus, and styloglossus muscles.
Where is the cribriform plate?
The cribriform plate (less commonly also called the lamina cribrosa of the ethmoid bone) is a sieve-like structure between the anterior cranial fossa and the nasal cavity. It is a part of ethmoid bone and supports the olfactory bulb, which lies in the olfactory fossa.
Is the cribriform plate part of the frontal bone?
The cribriform plate is the name given to a specific area of the human skull. It is part of the ethmoid bone, which is responsible for separating the brain from the nasal cavity. It attaches to a structure located on the frontal bone of the skull known as the ethmoidal notch.
What is the purpose of the cribriform plate?
The cribriform plate is part of the ethmoid bone , which is responsible for separating the brain from the nasal cavity.
Where is the trabecular bone located?
Trabecular bone is bone tissue arranged in a meshwork of thin plates or beams that is commonly found at the center of long bones and that constitutes a large part of the hip and vertebrae. Also called cancellous bone or spongy bone.
What is the function on cribriform plate?
Function of Cribriform Plate. The plate provides support to the olfactory bulb which is perforated by foramina to serve as a passage to the olfactory nerves . The openings in the Cribriform Plate comprises of nerves that enable humans to smell and differentiate between odors.
