The facial nerve (cn vii) passes through the opening in the temporal bone called the stylomastoid foramen.
<h3>Stylomastoid foramen:</h3>
The foramen between the styloid and mastoid processes of the temporal bone of the skull is known as the stylomastoid foramen. It serves as the facial canal's terminus and carries the facial nerve and stylomastoid artery. Bell's palsy may be brought on by facial nerve irritation in the stylomastoid foramen. An unexplained episode of facial muscular paralysis or weakening is known as Bell's palsy. Over the course of 48 hours, it gets worse suddenly.
The stylomastoid foramen is where the 7th cranial nerve leaves the skull and enters the parotid gland at its deep surface. The nerve splits into two major branches, the temporofacial branch, and the cervicofacial branch, right next to the parotid duct.

Answer: sweat glands!
Explanation: sweat glands are the only thing that secrete waste and sweat hence being called a “sweat gland”.
The role of cyclin-dependent kinases in the cell cycle is that, they stop the cycle if something has gone wrong.
Explanation:
In Eukaryotic cells cyclin-dependent kinases are universal regulator cell. It undergoes a constant cycle and degradation known as Mitotic and G1 cyclin. When cycle dependent cycle synthesize it acts like an activating protein and then bind to cyclin-dependent kinases forming cyclin-dependent kinases complex.
Now it acts as signal to the cell to pass the next phase of cell cycle. After its cyclin gets degraded, it deactivates the cyclin-dependent kinases and from particular phase signalling stop
