Buccal Mucosa Graft
Buccal may refer to: * Buccal, or buccal cavity, an oral body cavity (mouth), particularly the cheek cavity ** Buccal administration ** Buccal space, in the mouth * Buccal artery * Buccal branch of the facial nerve * Buccal nerve The buccal nerve (long buccal nerve) is a nerve in the face. It is a branch of the mandibular nerve (which is itself a branch of the trigeminal nerve) and transmits sensory information from skin over the buccal membrane (in general, the cheek) an ... {{disambig ...

Mouth
In animal anatomy, the mouth, also known as the oral cavity, or in Latin cavum oris, is the opening through which many animals take in food and issue vocal sounds. It is also the cavity lying at the upper end of the alimentary canal, bounded on the outside by the lips and inside by the pharynx. In tetrapods, it contains the tongue and, except for some like birds, teeth. This cavity is also known as the buccal cavity, from the Latin ''bucca'' ("cheek"). Some animal phyla, including arthropods, molluscs and chordates, have a complete digestive system, with a mouth at one end and an anus at the other. Which end forms first in ontogeny is a criterion used to classify bilaterian animals into protostomes and deuterostomes. Development In the first multicellular animals, there was probably no mouth or gut and food particles were engulfed by the cells on the exterior surface by a process known as endocytosis. The particles became enclosed in vacuoles into which enzymes were secr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Buccal Administration
Buccal administration is a topical route of administration by which drugs held or applied in the buccal () area (in the cheek) diffuse through the oral mucosa ( tissues which line the mouth) and enter directly into the bloodstream. Buccal administration may provide better bioavailability of some drugs and a more rapid onset of action compared to oral administration because the medication does not pass through the digestive system and thereby avoids first pass metabolism. As of May 2014, the psychiatric drug asenapine; the opioid drugs buprenorphine, naloxone, and fentanyl; the cardiovascular drug nitroglycerin; the nausea medication prochlorperazine; the hormone replacement therapy testosterone; and nicotine as a smoking cessation aid were commercially available in buccal forms, as was midazolam, an anticonvulsant, used to treat acute epileptic seizures. Buccal administration of vaccines has been studied, but there are challenges to this approach due to immune tolerance mechanis ...

Buccal Space
The buccal space (also termed the buccinator space) is a fascial space of the head and neck (sometimes also termed fascial tissue spaces or tissue spaces). It is a potential space in the cheek, and is paired on each side. The buccal space is superficial to the buccinator muscle and deep to the platysma muscle and the skin. The buccal space is part of the subcutaneous space, which is continuous from head to toe. Structure Boundaries The boundaries of each buccal space are: * the angle of the mouth anteriorly, * the masseter muscle posteriorly, * the zygomatic process of the maxilla and the zygomaticus muscles superiorly, * the depressor anguli oris muscle and the attachment of the deep fascia to the mandible inferiorly, * the buccinator muscle medially (the buccal space is superficial to the buccinator), * the platysma muscle, subcutaneous tissue and skin laterally (the space is deep to platysma). Communications * to the pterygomandibular space, infratemporal space, submassete ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Buccal Artery
The buccal artery (buccinator artery) is a small artery in the head. It branches off the second part of the maxillary artery and supplies the cheek and buccinator muscle. Course It runs obliquely forward, between the pterygoideus internus and the insertion of the temporalis, to the outer surface of the buccinator, to which it is distributed, anastomosing with branches of the facial artery and with the infraorbital. From the infraorbital area, it descends bilaterally in the superficial face along the lateral margin of the nose, then running anti-parallel to the facial artery The facial artery (external maxillary artery in older texts) is a branch of the external carotid artery that supplies structures of the superficial face. Structure The facial artery arises in the carotid triangle from the external carotid arte ... across the lateral oral region. Additional images file:Gray508.png, The arteries of the face and scalp.

Buccal Branch Of The Facial Nerve
The buccal branches of the facial nerve (infraorbital branches), are of larger size than the rest of the branches, pass horizontally forward to be distributed below the orbit and around the mouth. Branches The ''superficial branches'' run beneath the skin and above the superficial muscles of the face, which they supply: some are distributed to the procerus, joining at the medial angle of the orbit with the infratrochlear and nasociliary branches of the ophthalmic. The ''deep branches'' pass beneath the zygomaticus and the quadratus labii superioris, supplying them and forming an infraorbital plexus with the infraorbital branch of the maxillary nerve. These branches also supply the small muscles of the nose. The ''lower deep branches'' supply the buccinator and orbicularis oris, and join with filaments of the buccinator branch of the mandibular nerve. Muscles of facial expression The facial nerve innervates the muscles of facial expression. The buccal branch supplies these mu ...
