Question | Answer |
---|---|
Corticoids | hormones secreted by the three cell layers of the adrenal cortex |
Cretinism | dwarfism caused by hypo-secretion of the thyroid gland |
Cushing's Syndrome | condition caused by hypersecretion of glucocorticoids from adrenal cortex |
Diabetes Inspidus | condition resulting from hyposecretion of ADH in which large volumes of urine are formed and if left untreated, may cause serious health problems |
Diabetes Mellitus | condition resulting when pancreatic islets secrete too little insulin, resulting in increased levels of blood glucose |
Endocrine | secreting into blood or tissue fluid rather than into a duct |
Exocrine | secreting into a duct |
Exophthalmos | abnormal protrusion of the eyes |
Gigantism | condition produced by hypersecretion of growth hormone during early years of life; results in child who grows to gigantic size |
Glucocorticoids | hormones that influence carbs, fats, and protein metabolism; secreted by adrenal cortex |
Gluconeogenesis | formulation of glucose or glycogen from protein or fat compounds |
Goiter | enlargement of the thyroid gland |
Hormone | substance secreted by endocrine gland and transported in the blood |
Mineralocorticoids | hormone that influences mineral salt metabolism secreted by adrenal cortex, aldosterone is the chief mineralocorticoid |
Myxedema | condition caused by deficiency of thyroid hormone in adults |
Parathyroid glands | set of glands located on the surface of the thyroid gland |
Prostaglandins | group of naturally occuring fatty acids that affect many body functions |
Target cells | organ or cell acted on by particular hormone and responding to it |
Anosmia | complete or partial loss of sense of smell |
Anopia | absence of an eye |
Aqueous humor | thin, clear watery fluid that fills space between cornea and the lens |
Blepharitis | inflammation of the eyelid margins |
Choroid | middle, vascular layer of the eye |
Cochlea | coiled tube in the inner ear |
Conjunctivitis | inflammation of the conjunctiva |
Cornea | transparent front part of the eye tat covers the iris, pupil, and anterior chamber |
Cranial Nerve | a nerve that arises from the underside of the brain or the brainstem |
Diplopia | double vision |
Hemianopia | blindness in one half of the visual field |
Iris | colored muscular part of the eye |
Labyrinth | complex system of connecting chambers and tubes of inner ear |
Lacrimal Gland | tear gland |
Sclera | tough outer protective layer of the eye |
Somatic Nervous System | consist of cranial and spinal nerve fibers that connect the CNS to the skin and skeletal muscles. Controls conscious activities |
Special Senses | senses that stem from receptors associated with specialized sensory organs; nose, eye, ear, tongue |
Tympanic membrane | eardrum |
Vitreous Humor | clear jellylike substance within the posterior cavity of the eye |
Afferent neurons | sensory neurons |
Arachnoid mater | delicate, web-like middle layer of meninges |
Ascending tracts | nerve tracts in the spinal cord that carry information to the brain |
Descending tracts | nerve tracts in the spinal cord that carry information from the brain to the muscles and gands |
Dura mater | tough outer layer of meninges |
Efferent neurons | motor neurons |
Gyri | ridges or convolutions on the surface of the cerebrum separated by shallow grooves called a sulcus or deep groove called a fissue |
motor neuron | efferent neurons carry impulse out of brain or spinal cord to muscles or glands |
Resting potential | difference in electrical charge between inside and outside of an undisturbed nerve cell membrane |
