telomerase
The enzyme that is concerned with
the formation, maintenance, and renovation of
telomeres, the ends of chromosomes.
telomere
The end of a chromosome. The ends of
chromosomes are specialized structures that are
involved in the replication and stability of DNA mol-
ecules. A telomere is a length of DNA that is made
up of a repeating sequence of six nucleotide bases
(TTAGGG). Small numbers of these terminal
TTAGGG sequences are lost from the tips of the
chromosomes, but the addition of TTAGGG repeats
by the enzyme telomerase compensates for this loss.
temperature
The specific degree of hotness or
coldness of the body. The normal body temperature
is generally considered to be 37° C (98.6° F).
However, the normal body temperature may range
between 36.1 to 37.2° C (97° and 99° F) during the
day. The body temperature at the beginning of the
day, when a person first arises, is called the basal
temperature. See also 
thermometer.
temple
The area just behind and to the side of the
forehead and the eye, above the side of the zygo-
matic arch (cheekbone) and in front of the ear.
temporal 1
Pertaining to the temple region of the
head. For example, the temporal lobe of the brain is
so named because of its anatomic location beneath
the temple.
2
Pertaining to time, limited in time,
temporary, or transient.
temporal arteritis
See 
arteritis, cranial.
temporal bone
A large irregular bone that is sit-
uated at the base and side of the skull. The tempo-
ral bone is connected with the mandible (the
jawbone) via the temporomandibular joint.
temporal lobe
The lobe of the cerebral hemi-
sphere on the side of the brain just forward of the
occipital lobe. The temporal lobe is located beneath
the temple region of the head. The temporal lobe
contains the auditory cortex, which is responsible
for hearing. It is also the site of the seizure activity
that is characteristic of temporal lobe epilepsy. See
also 
epilepsy, temporal lobe.
