| communicating junction | <cell biology> Another name for a gap junction. (05 Jan 1998) |
| mucocutaneous junction | The site of transition from epidermis to the epithelium of a mucous membrane. (05 Mar 2000) |
| muscle-tendon junction | The union of a muscle and tendon fibre in which sarcolemma intervenes between the two; the end of the muscle fibre may be rounded, conical, or tapered. Synonym: muscle-tendon junction. (05 Mar 2000) |
| costochondral junction | <anatomy> The point where the ribs articulate with the sternum (cartilaginous articulation). (10 Nov 1998) |

| septate junction | An intercellular junction found in invertebrate epithelia that is characterised by a ladder like appearance in electron micrographs. Thought to provide structural strength and to provide a barrier to diffusion of solutes through the intercellular space. Occur widely in transporting epithelia and are controversially considered analogous to tight junctions (zonula occludens). (18 Nov 1997) |
