| branchial apparatus | The aggregate of the pharyngeal arches, pouches, clefts, and membranes seen in the developing embryo of vertebrates. (05 Mar 2000) |
|---|---|
| branchial arches | Typically, 6 arch's in vertebrates; in the lower vertebrates, they bear gills; in the higher vertebrates, they appear transiently and give rise to specialised structures in the head and neck. Synonym: pharyngeal arches, visceral arches. (05 Mar 2000) |
| branchial cartilages | Cartilage's developing within the vertebrate or embryonic branchial arches; they form the cartilaginous viscerocranium. Synonym: pharyngeal cartilages. (05 Mar 2000) |
| branchial cleft cyst | Also called a branchial cyst, this is a cavity that is a remnant from embryologic development present at birth in one side of the neck just in front of the large angulated muscle on either side (the sternocleidomastoid muscle). The cyst may not be recognised until adolescence as it enlarges its oval shape. Sometimes it develops a sinus or drainage pathway to the surface of the skin from which mucus can be expressed. Total surgical excision is the treatment of choice. Recurrence is not expected. (12 Dec 1998) |
| branchial clefts | A bilateral series of slitlike openings into the pharynx through which water is drawn by aquatic animals; in the walls of the cleft's are the vascular gill filaments that take up oxygen from the water passing through the cleft's; sometimes loosely applied to the branchial ectodermal grooves of mammalian embryos, which are imperforate, rudimentary homologues of complete gill clefts. Synonym: gill clefts. (05 Mar 2000) |

Total surgical excision is the treatment of choice. Recurrence is not expected. (12 Dec 1998) |
| branchial efferent column | A column of gray matter in the brainstem of the embryo, represented in the adult by the nucleus ambiguus and the motor nuclei of the trigeminal and facial nerves. (05 Mar 2000) |
| branchial fissure | A persistent branchial cleft. (05 Mar 2000) |
| branchial fistula | A congenital fistula in the neck resulting from incomplete closure of a branchial cleft. (05 Mar 2000) |
| branchial groove | An external embryonic groove between contiguous branchial arches. See: branchial clefts. (05 Mar 2000) |
| branchial mesoderm | Mesoderm surrounding the primitive stomodeum and pharynx; it develops into the pharyngeal arches. (05 Mar 2000) |
| branchial pouches | pharyngeal pouches |
| branchial region | Region containing paired arched columns that bear gills in lower aquatic vertebrates and appear in the embryos of higher vertebrates in comparable form. In higher vertebrates the arches are subsequently modified into structures of the neck and ear. (12 Dec 1998) |
| branchiate | <anatomy> Furnished with branchiae; as, branchiate segments. Source: Websters Dictionary (01 Mar 1998) |
| branchiferous | <anatomy> Having gills; branchiate; as, branchiferous gastropods. Source: Websters Dictionary (01 Mar 1998) |

| bran |
A hero god, protector of poetry and the underworld. Bran ("raven"), son of Llyr and Penarddun, and brother of Branwen and Manawydan. He is associated with a cauldron of regeneration which would revive the dead while leaving them voiceless. Bran's cauldron is destroyed, and he is mortally wounded in the war to rescue his sister Branwen, so he instructed his followers to decapitate him and carry the head to London and bury it, where it would become a defense and a protection to the whole Isle.

| brain |
The part of the central nervous system situated within the skull. It includes two cerebral hemispheres ?parallel masses of deeply furrowed tissue ?as well as the brainstem and cerebellum. Its functions include muscle control and coordination, sensory reception and integration, speech production, memory storage, and the elaboration of thought and emotion.
