The external acoustic meatus is a foramen in which skull bone?
It is located on temporal side of the skull and it is where sounds enters the human ear leading to the tympanic membrane. It is sometimes referred to as the extermal auditory canal.
What is the prominent bulge just posterior and inferior to the external auditory meatus?
The prominent bulge just posterior and inferior to the external auditory meatus is the mastoid process of the temporal bone. This bony prominence serves as an attachment site for several muscles involved in head movement and provides protection to the structures within the mastoid air cells.
What is an acanthiomeatal line?
The definition for the word acanthiomeatal line is "a hypothetical line extending from the external acoustic meatus to the acanthion. In dentistry a full maxillary denture is constructed so that its occlusal plane is parallel with this line. The line is used for radiographic positioning of the skull."
What is A long-tube like passageway in a bone?
Medullary Cavity. Answer for canal-like structure in the bone is : MEATUS.
What is the external sheath or covering on a bone called?
The external sheath or covering on a bone is called the periosteum. It is a fibrous membrane that contains blood vessels and nerves and helps in bone growth and repair.

What is mri internal auditory meatus both?
An MRI (magnetic resonance imaging) is a tool used to examine internal body structures. An MRI of the internal auditory meatus is an MRI scan used to look for a problem with the nerves supplying the inner ear.
What is the function of internal auditor meatus?
The internal auditory meatus is a canal in the temporal bone of the skull that serves as a passageway for nerves and blood vessels. It primarily allows the facial nerve (cranial nerve VII) and the vestibulocochlear nerve (cranial nerve VIII) to enter the inner ear. Additionally, it contains the auditory and vestibular structures essential for hearing and balance. The meatus plays a crucial role in connecting the inner ear to the brain, facilitating auditory and vestibular functions.
What is the opening leading toward the ear drum on temporal bone?
The opening leading toward the ear drum on the temporal bone is called the external acoustic meatus, also known as the ear canal. It is the pathway that directs sound waves into the ear canal towards the eardrum.
What is the site ofthe mastoid process in cranium?
The mastoid process is a bony protuberance on the temporal bone, just posterior and inferior to the external auditory meatus. It can be felt under the skin just behind and below the ear.
What is an acanthiomeatal line?

What types of bones are the foramen and meatus bones?
The foramen and meatus are not bones. They are bone markings -- each is an opening in a bone.

Medullary Cavity. Answer for canal-like structure in the bone is : MEATUS.
What bone marking is a canal like structure?
meatus
What is the function of the internal auditory meatus?
The internal auditory meatus is a canal in the temporal bone of the skull that serves as a passageway for the facial nerve (cranial nerve VII) and the vestibulocochlear nerve (cranial nerve VIII), which are crucial for hearing and balance. It also allows for the entry of blood vessels and other structures supplying the inner ear. This anatomical feature plays a vital role in transmitting sensory information from the inner ear to the brain.
A canal leading through the matrix of a bone is termed a?
meatus
