Human salivary glands produce between 0.5 to 1.5 L of saliva daily, facilitating mastication, swallowing, and speech, lubricating the oral mucosa, and providing an aqueous medium for taste perception. They also participate in the digestion of triglycerides and starches by secreting lipases and ...
Laryngeal innervation is intricate and detailed, representing some of the more complex relationships in head and neck anatomy (see Image.Nerves of the Thorax). The vagus nerve innervates the laryngeal structures through various branches. The superior laryngeal nerve, external and internal superior laryn...
The human tongue plays a role in multiple actions, including swallowing, chewing, speaking, and breathing. The tongue is in the oral cavity; it is a muscular organ that extends from the hyoid bone in the neck to the floor of the mouth. The tongue's function is to move and push food ...
We conclude that precise knowledge on OM might be very helpful not only to students in medicine and dentistry during anatomical dissection courses, but also to head and neck surgeons, ear–nose–throat specialists and neurosurgeons working in this fieldAndre...
The human respiratory system is comprised of special organs designed to take in oxygen for the air we breathe and expel carbon monoxide, keeping us alive. Let's take a closer look at these organs and explore respiratory physiology in more detail.
Located in the lower neck and thorax, within the superior mediastinum Continuous superiorly with the larynx at the level of C6 Ends inferiorly at the level of T5 and continues as the primary bronchi and the rest of the bronchial tree in the lungs Shape and structure: The trachea is a...
The homunculus is known as the "little person' in the brain because it has a topographical map of the whole human body in a small area of the cerebral cortex. There is one for the motor cortex in the frontal lobe and one for the somatosensory cortex in the parietal lobe. ...
Thelarynx, also known as the voice box, is a small hollow tube in the throat that sits between the fourth and sixth cervical vertebrae and in front of the esophagus. It is situated around the middle of the neck. Originating from the Greek wordlaryngosmeaning theupper windpipe,the larynx's...
less, not push up against the skin of the neck, and ultimately be less visible. In both sexes, regardless of the angle, the primary function of the Adam’s Apple is the same as that of the thyroid cartilage it comprises, to protect the vocal cords immediately behind and inferior to it...
Thevagus nerveis another key part of the anatomy of the pharynx. It runs through the face, neck, and abdomen and transmits messages to and from the brain. Among other things, the vagus nerve helps control the motor and sensory functions of the pharynx, including swallowing. ...
