SIMILAR TERMS--------------------------------------
PREVIOUS AND NEXT TERMS--------------------------------------
Spermatozoa
(singular, spermatozoon) The male gamete; a haploid, usually small, flagellated cell.
Skin
Skin is an organ of the integumentary system; which is composed of a layer of tissues that protect underlying muscles and organs. Skin is used for insulation, vitamin D production, sensation, and excretion (through sweat).
Sex
An individual's gender classification - male or female.
Second Messenger
Molecules that are synthesized in response to hormones binding to their receptors. Second messengers initiate the biological action of the hormone.
Serotonin
A neurotransmitter important in filtering out information. If its levels are low, it can be the underlying cause of depression and violence.
Sibling
Spinal cord
The ovoid column of nervous tissue, extending from the medulla to the second lumbar vertebra in the spinal canal. All nerves to the trunk and limbs issue from the spinal cord, the center of reflex action containing conducting paths to and from the brain. Sensory neurons enter posteriorly; motor nerves arise anteriorly.
Schizophrenia
Any of a group of psychotic disorders usually characterized by withdrawal from reality, illogical patterns of thinking, delusions, and hallucinations, and accompanied in varying degrees by other emotional, behavioral, or intellectual disturbances. Schizophrenia is associated with dopamine imbalances in the brain and defects of the frontal lobe and is caused by genetic, other biological, and psychosocial factors. It is mainly treated by antipsychotic drugs which block Dopamine receptors such as Haloperidol.
Sinusitis
Inflammation of the sinuse (hollow spaces in the bone of the cheeks and forehead), due to an infection or an allergic reaction. Probably the most common cause of pain in and around the eye. Symptoms include head pain (headache, pain around the eyes, toothache, jaw pain), nasal discharge, postnasal drip, coughing, eyelid swelling, swelling around the eyes, a stuffy nose, fatigue, bad breath and a sore throat.
Spasticity
Involuntary muscle tightness and stiffness that occurs in about two-thirds of people with cerebral palsy and in many who suffer severe head injuries. The medical definition of dystonia is a velocity-dependent, increased resistance to passive muscle stretch. In other words, when a muscle affected by spasticity is stretched by someone else, it is harder to move the muscle than normal, and the faster one pushes, the harder the muscle is to move.
Spina Bifida
A neural tube defect resulting from the improper closure of the fetal spine. The defect can be low in the spine and problems are often mild. If the defect is higher in the spine it can cause more serious problems such as leg paralysis and & bladder control.
