sebum

A

(sē′bŭm) Secretion of a sebaceous gland.

146

147
Q

serological testing

A

Techniques for identifying a microorganism based on its reaction with antibodies.

148
Q

Shade avoidance syndrome

Developmental strategy of plants that enables adaptation to the canopy shade; responses are induced by high levels of far-red light below canopy shade.

149
Q

silica

A

A silicate crystal that has a formula unit of SiO2; also called quartz.

150
Q

soda-lime glass

A

A type of glass that is about 70% SiO2 with the balance being mostly Na2O and CaO. This type of glass is transparent to visible light (not ultraviolet) and has a high thermal expansion, but it is less expensive to make and form into desired shapes than vitreous silica.

A

The removal of all microorganisms, including endospores.

157
Q

stretch shortening cycle (SSC)

A

A combination of eccentric and concentric muscle actions.

158
Q

subcutaneous mycosis

A

A fungal infection of tissue beneath the skin.

159
Q

superficial

A

(sū-per-fish′ăl) Toward the surface.

160
Q

Symmetry-allowed, symmetry-disallowed

A

A symmetry-allowed reaction is a pericyclic process that has a favorable orbital symmetry for reaction through a concerted pathway. A symmetry-disallowed reaction is one that does not have favorable orbital symmetry for reaction through a concerted pathway.

161
Q

synergist muscle

A

A muscle that contracts with other muscles to produce movement in one direction.

162
Q

tachycardia

A

(tak′i-kar′dē-ă) Resting heart rate above 100 beats per minute.

163
Q

tegmentum

A

The part of the midbrain lying ventral to the cerebral aqueduct.

164
Q

Thalassemia

A

Underproduction of hemoglobin α-chains (α-thalassemia) or β-chains (β-thalassemia).

165
Q

Thermosetting resins

A

Polymers that become highly cross-linked and solidify into a hard, insoluble mass when heated.

166
Q

tincture

A

A solution in aqueous alcohol.

167
Q

torr

A

A unit of pressure named after Evangelista Torricelli and equivalent to 1/760 of an atmosphere (atm).

168
Q

trans face

A

Face on the other (far) side.

169
Q

Tree diagram

A

A diagram used in NMR to sort out the complicated splitting patterns that can arise from multiple couplings.

170
Q

tubercle

A

(tū′ber-kl) Nodule or slight elevation from the surface of a bone that allows attachment of a tendon or ligament.

171
Q

umbilical

A

(ŭm-bil′i-kăl) Relating to the umbilicus (navel).

172
Q

Upield

A

The right-hand portion of the NMR chart.

173
Q

vapor pressure lowering (ΔP)

A

The change in vapor pressure that occurs in pure substance upon addition of a solute.

174
Q

ventricular system

A

The cerebrospinal fluid–filled spaces inside the brain, consisting of the lateral ventricles, third ventricle, cerebral aqueduct, and fourth ventricle.

175
Q

vestibular system

A

The neural system that monitors and regulates the sense of balance and equilibrium.

176
Q

visual field

A

The total region of space viewed by both eyes when the eyes are fixated on a point.

177
Q

volt

A

The SI unit of potential difference; defined as 1 J/C.

178
Q

Wernicke–Geschwind model

A

A model for language processing involving interactions of Broca’s area and Wernicke’s area with sensory and motor areas.

179
Q
