What are the contents of submandibular triangle?
The following summarizes the important structures found in the submandibular triangle:
- The external and internal carotid artery.
- The internal jugular vein.
- The deep cervical lymph nodes.
- The 10th cranial nerve ( Vagus Nerve )
- The submandibular gland.
- The submandibular lymph nodes.
- The Facial artery and vein.
What are the contents of the carotid triangle?
The carotid triangle includes the common carotid artery and its bifurcation into the external carotid artery (ECA) and internal carotid artery (ICA). It usually contains the superior thyroid, lingual, facial, occipital, and ascending pharyngeal arteries.
What does submandibular gland secrete?
About the size of a walnut, the submandibular glands are located below the jaw. The saliva produced in these glands is secreted into the mouth from under the tongue. Like the parotid glands, the submandibular glands have two parts called the superficial lobe and the deep lobe.
What are the contents of digastric triangle?
The digastric triangle houses submandibular gland and lymph nodes (anteriorly), caudal part of the parotid gland (posteriorly), facial artery and vein, submental artery and vein, lingual arteries and veins, mylohyoid nerve and the hypoglossal nerve (CN XII).
Which triangle is the submandibular gland found?
The submandibular gland is located in the submandibular triangle, below the mylohyoid muscle, with its posterior portion wrapped around the posterior border of the mylohyoid and extending anteriorly for a short distance.
What is the submandibular triangle?
The submandibular triangle, also known as the digastric triangle, is bounded anteriorly by the anterior belly of the digastric muscle, posteriorly by the posterior belly of the digastric muscle, superiorly by the mandible, and inferiorly by the mylohyoid and hypoglossus muscles.
What fluid do salivary glands produce?
saliva
salivary gland, any of the organs that secrete saliva, a substance that moistens and softens food, into the oral cavity of vertebrates.
What are the contents of saliva?
Saliva is composed of a variety of electrolytes, including sodium, potassium, calcium, magnesium, bicarbonate, and phosphates. Also found in saliva are immunoglobulins, proteins, enzymes, mucins, and nitrogenous products, such as urea and ammonia.
Which enzyme is present in saliva?
Salivary amylase is a glucose-polymer cleavage enzyme that is produced by the salivary glands.
Where is submandibular area?
The submandibular space is a fascial space of the head and neck (sometimes also termed fascial spaces or tissue spaces). It is a potential space, and is paired on either side, located on the superficial surface of the mylohyoid muscle between the anterior and posterior bellies of the digastric muscle.
What are the 4 components of saliva?
It is composed of water, mucus, proteins, mineral salts, and amylase. As saliva circulates in the mouth cavity it picks up food debris, bacterial cells, and white blood cells.
What minerals are found in saliva?
The main components of saliva electrolytes are sodium, calcium, copper, magnesium, bicarbonates, and organic phosphates. Increase in calcium level in the remineralization solution may enhance the deposition velocity of minerals in the caries lesion.
Where is amylase found?
Amylase is a digestive enzyme predominantly secreted by the pancreas and salivary glands and found in other tissues in very small levels[1].
What is amylase?
Amylase is an enzyme, or special protein, that helps you digest carbohydrates. Most of the amylase in your body is made by your pancreas and salivary glands.
What is neck triangle?
The triangles of the neck are the topographic areas of the neck bounded by the neck muscles. The sternocleidomastoid muscle divides the neck into the two major neck triangles; the anterior triangle and the posterior triangle of the neck, each of them containing a few subdivisions.
What structures are found in the submandibular triangle?
The following summarizes the important structures found in the submandibular triangle: 1. The external and internal carotid artery 2. The internal jugular vein 3. The deep cervical lymph nodes 4. The 10th cranial nerve ( Vagus Nerve ) 5.
What is the blood supply to the submandibular gland?
The blood supply to the gland comes from the facial artery and lingual artery. The parasympathetic and sympathetic nervous systems stimulate the salivary glands. The submandibular gland produces saliva, which moistens the mouth and aids in chewing, swallowing, digestion, and helps to keep the mouth and teeth clean.
Where does the facial artery enter the submandibular triangle?
The facial artery (which is the fourth branch of the external carotid artery) also enters the submandibular triangle by passing beneath the posterior belly of the digastric muscle, as well as the stylohyoid muscle.
What is the anterior part of the submandibular gland?
The anterior part contains the submandibular gland, superficial to which is the anterior facial vein, while imbedded in the gland is the facial artery and its glandular branches. Beneath the gland, on the surface of the Mylohyoideus, are the submental artery and the mylohyoid artery and nerve.
