what is the function of the anterior fossa?

The anterior cranial fossa is the most shallow and superior of the three cranial fossae. It lies superiorly over the nasal and orbital cavities. The fossa accommodates the anteroinferior portions of the frontal lobes of the brain.

Function. Tibialis anterior is the primary dorsiflexor of the ankle with synergistic action of extensor hallicus longus, extensor digitorium longus and peroneous tertius. Inversion of the foot. Adduction of the foot.

The main function of the facial nerve is motor control of all of the muscles of facial expression. It also innervates the posterior belly of the digastric muscle, the stylohyoid muscle, and the stapedius muscle of the middle ear.

Function. The ACL provides approximately 85% of total restraining force of anterior translation. It also prevents excessive tibial medial and lateral rotation, as well as varus and valgus stresses. To a lesser degree, the ACL checks extension and hyperextension.

Axial muscles support and move the head and spinal column, function in non- verbal communication by affecting facial features, move the lower jaw during chewing, assist in food processing and swallowing, aid breathing, and support and protect the abdominal and pelvic organs.

The appendix, notorious for its tendency to become inflamed or even rupture, has historically been viewed as a vestigial organ with no real function. But new research supports the idea that the appendix may indeed serve a purpose: to protect beneficial bacteria living in the gut.

There are two muscles which serve a protective function in the middle ear; the tensor tympani and stapedius. They contract in response to loud noise, inhibiting the vibrations of the malleus, incus and stapes, and reducing the transmission of sound to the inner ear.

The anterior median fissure provides a groove in which the anterior spinal artery sits. From here, it provides the anterior part of the spinal cord. It is sourced from the segmental medullary arteries and the segmental spinal arteries which are sourced from the intercostal arteries.

The function of the serratus anterior muscle is to allow the forward rotation of the arm and to pull the scapula forward and around the rib cage. The scapula is able to move laterally due to the serratus anterior muscle, which is vital for the elevation of the arm.

Structure and Function The principal function of the small intestine is to break down food, absorb nutrients needed for the body, and get rid of the unnecessary components.

The anterior pituitary regulates several physiological processes including stress, growth, reproduction, and lactation. Its regulatory functions are achieved through the secretion of various peptide hormones that act on target organs including the adrenal gland, liver, bone, thyroid gland, and gonads.

The major task of the ear is to detect, transmit and transduce sound. Another very important function of the ear is to maintain our sense of balance.

The brainstem has many basic functions, including regulation of heart rate, breathing, sleeping, and eating. It also plays a role in conduction. All information relayed from the body to the cerebrum and cerebellum and vice versa must traverse the brainstem.
382048
The tympanic membrane's function is to assist in human hearing. When sound waves enter the ear, they strike the tympanic membrane. The membrane vibrates with the force of the sound wave strike and transmits the vibrations further in, to the bones of the middle ear.

Medulla – The primary role of the medulla is regulating our involuntary life sustaining functions such as breathing, swallowing and heart rate. As part of the brain stem, it also helps transfer neural messages to and from the brain and spinal cord. It is located at the junction of the spinal cord and brain.
696155
Cranial nerve XI innervates the motor function of the trapezius. The function of the trapezius is to stabilize and move the scapula. The upper fibers can elevate and upwardly rotate the scapula and extend the neck.

The internal obliques function bilaterally (both sides) to flex the trunk and compress its contents. They function unilaterally (one-sided) to laterally flex the trunk and rotate it to the same side.
