A. in life vessels ran through those openingsB. in life nerves ran through those openings
What is the significance of temporal opening in skull?
Temporal openings in the skull allow for muscles to pass through and connect to the jaw, enabling jaw movement for activities such as chewing and speaking. Additionally, these openings provide a passage for blood vessels and nerves to reach the face and head.
Where do the cranial nerves exit?
The cranial nerves exit from the brainstem. They emerge from specific openings in the skull called foramina, which are small bony passageways. These openings provide a pathway for the cranial nerves to exit the skull and innervate different parts of the head and neck.
What is a large mass of nerves located in the skull?
The brain is a large mass composed of nerves that rests in the skull.
What nerves exit from skull through jugular foramen?
The glossopharyngeal (CN IX) and Vagus (X) exit the skull through the jugular foramen.
What protects the nerves of the brain?
the skull
How many foramen are there in the body?
There are numerous foramen in the human body, located within different bones and tissues. These openings provide passages for nerves, blood vessels, and other structures to pass through. Some examples include the foramen magnum at the base of the skull and the intervertebral foramina in the spinal column.
What is the PNS made up of?
it is made up by nerves and associated cells that are not part of the brain and the spinal cord, included here are cranial nerves that pass through openings in the skull and stimulate regions of the head and neck, spinal nerves, and ganglia(ganglia are collections of nerve cell bodies).
What is an anapsid?

Why is it important for the skull to have holes through the bone?
So nerves and blood vessels can get out. Otherwise, it'd be like having a second floor on your house with no windows, doors, or stairs.
