| intrinsic muscles of foot | Muscles fully contained (origin, belly, insertion) in the foot and toes. These muscles are arranged in four layers and all are innervated by the plantar branches of the tibial nerve. Although they may be capable of producing the actions described under their individual entries, as a group the primary function of the intrinsic muscles of the foot is to provide dynamic support of the longitudinal arch of the foot, resisting the forces which act momentarily to spread the arch during walking and running.

| intrinsic pathway | <haematology> Initiation of blood clotting as a result of factors released from damaged tissue, as opposed to contact with a foreign surface (the intrinsic pathway). Tissue thromboplastin (Factor III) in conjunction with Factor VII proconvertin) will activate Factor X that, once activated, converts prothrombin to thrombin. (27 Jun 1999) |
| intrinsic proteins | Proteins that cannot be easily separated from a biomembrane. Synonym: intrinsic proteins. (05 Mar 2000) |
| intrinsic reflex | A reflex muscular contraction elicited by the application of a stimulus, usually stretching, to the muscle itself as opposed to a muscular contraction caused by an extrinsic stimulus, e.g., skin, as in the abdominal skin reflex's. (05 Mar 2000) |
| intrinsic sphincter | A thickening of the circular fibres of the muscular coat of an organ. (05 Mar 2000) |
| intrinsic sympathomimetic activity | The property of a drug that causes activation of adrenergic receptors so as to produce effects similar to stimulation of the sympathetic nervous system. (05 Mar 2000) |
| tonoplast intrinsic protein | <protein> Plant protein, closely related to major intrinsic protein. Found in plant storage vacuolar membranes. (18 Nov 1997) |
