| unconditioned response | A response, such as salivation, which is a part of the animal or human repertoire. Compare: conditioned response. (05 Mar 2000) |

| flight or fight response | See: emergency theory. (05 Mar 2000) |
| late-phase response | Recurrence of symptoms after an appreciable interval following challenge with an antigen; preceded by an initial early-phase response. (05 Mar 2000) |
| lh response to gnrh | This test measures the level of luteinising hormone in the blood after an injection of gonadotrophin releasing hormone (GNRH), normally produced in the hypothalamus. This will test the ability of the pituitary gland to respond by measuring one of the pituitary glands byproducts, luteinising hormone. This test is used to differentiate hypogonadism (ovary or testes) into primary hypogonadism (problem is with the ovary or testes) or secondary hypogonadism (problem is with the pituitary gland or the hypothalamus). (27 Sep 1997) |
| lymphoproliferative response | <haematology, immunology> A specific immune response that entails rapid T-cell replication. Standard antigens, such as tetanus toxoid, that elicit this response are used in lab tests of immune competence. (13 Nov 1997) |
| air cells of auditory tube | Occasional small air cells in the inferior wall of the auditory tube, near the tympanic orifice, communicating with the tympanic cavity. Synonym: cellulae pneumaticae tubae auditivae, air cells of auditory tube. (05 Mar 2000) |
| auditory | <otolaryngology> Pertaining to the sense of hearing. Origin: L. Auditorius (18 Nov 1997) |
| auditory agnosia | The inability to recognise sounds, words, or music; caused by a lesion of the auditory cortex of the temporal lobe. (05 Mar 2000) |
| auditory alternans | Alternation in the intensity of heart sounds or murmurs in the presence of a regular cardiac rhythm as a result of alternation of the heart. Synonym: auditory alternans. (05 Mar 2000) |
| auditory aphasia | An impairment in comprehension of the auditory forms of language and communication, including the ability to write from dictation in the presence of normal hearing. Spontaneous speech, reading, and writing are not affected. Synonym: acoustic aphasia, word deafness. (05 Mar 2000) |
| auditory area | Area of the temporal lobe concerned with hearing. (12 Dec 1998) |
| auditory canal | The passage leading inward through the tympanic portion of the temporal bone, from the auricle to the tympanic membrane; it consists of a bony (inner) portion and a fibrocartilaginous (outer) portion, the cartilaginous external acoustic meatus. Synonym: meatus acusticus externus, acoustic meatus, antrum auris, auditory canal, external auditory meatus. (05 Mar 2000) |
| auditory capsule | The cartilage that, in the embryo, surrounds the developing auditory vesicle and develops into the bony labyrinth of the inner ear. (05 Mar 2000) |
| auditory cortex | Area of the temporal lobe concerned with hearing. (12 Dec 1998) |
| auditory diseases, central | Diseases of the auditory pathways from the bulbar cochlear nuclei to the auditory cortex in the temporal lobe. Structures involved include the medial and lateral lemnisci, inferior colliculus, and the medial geniculate nucleus. (12 Dec 1998) |
