Explanation:
Vestibule portion of the nasal cavity is lined with sebaceous and sweat glands and numerous hair follicles.
<h3>What is vestibule?</h3>
- A vestibule is a tiny room that leads into a larger space, like a lobby, entrance hall, or hallway.
- It serves as a place to wait, block the view of the bigger space, stop heat loss, provide space for storing outside clothing, etc.
- A vestibule is something like the tiny space outside the main bank where you enter and where the ATM is stored.
- A vestibule is, for instance, the middle cavity of the inner ear that connects to the eardrum.
- A vestibule is a little opening or chamber at a canal's start.
- The urinary meatus (urethral opening) and the vaginal opening both open into the vulvar vestibule, which is a portion of the vulva between the labia minora.

Answer:
By action potential nerve contract the muscle
Explanation:
The muscle contract when the nervous system sends action potential to the muscle. So the nervous system delivers signal to muscle, the first signal reaches the neuromuscular junction. The signals are passed by a chemical messenger called neurotransmitter release by motor neurons, the chemicals bring reaction and shorten the muscle fibre. When neurotransmitter are absent or reduce in concentration the process reverse and muscle relax again.
The structural commonality of the biceps brachii and the rectus abdominis is that they are parallel muscles whose fibers run along through the long axis of the body.
Together with the pyramidalis muscle, the rectus abdominis is a member of the anterior abdominal muscles. However, when considering the functional architecture, these two muscles, together with the three lateral abdominal muscles—the external oblique, internal oblique, and transversus abdominis make up the anterolateral abdominal wall.
The biceps brachii muscle, also known as the "biceps," is a big, thick arm muscle with two heads. The supraglenoid tubercle, located above the glenoid cavity of the scapula, is the location of the long head. It is extra synovial while being in the intracapsular area.
At the humeral head, the long biceps tendon curves sharply before continuing on in the bicipital groove (intertubercular sulcus). Ligaments in the capsular region (also known as the biceps pulley) hold this pivotal point in place.
Short head: Arises at the coracoid process of the scapula, where it partially fuses with the coracobrachialis origin tendon.
