contained within the cranium

brain and spinal cord

clear, colorless fluid contained in ventricles; cushions brain and spinal cord from shock, transports nutrients, and clears metabolic waste

largest portion of the brain; divided into left and right hemispheres

three layers of membrane that cover the brain and the spinal cord

cordlike structure that carries impulses from one part of the body to another

system of nerves extending from the brain and spinal cord

passes through the vertebral canal; conducts nerve impulses to and from the brain

disease charaterized by early dementia, confusion, loss of recognition of persons or familiar surroundings, restlessness, and impaired memory

jarring or shaking that results in injury; may be caused b slight or severe head injury; symptons include vertigo, headache, and loss of consciousness

disorder caused by inc. amoount of CSF in the ventricles of the brain, which cause enlargement of the cranium in infants

diagnostic procedure performed by insertion of a needle into the subarachnoid space usually between the 3rd and 4th lumbar vertebrae

degenerative disease characterized by sclerotic patches along the brain and spinal cord

paralysis from the waist down caused by damage to the lower level of spinal cord

chronic degenerative disease of the central nervous system; symptoms include resting tremors of the hands and feet; rigidity, expressionless face, and shuffling gait

sudden attack with an involuntary series of contractions

disorder caused by interruption of blood supply to a region of the brain, depriving nerve cells in the affected area of oxygen and nutrients; cells may be damaged or die within minutes. Speech, movement, memory, and other CNS functions may be affected in varying degrees.

bleeding caused by a ruptured blood vessel just outside the brain(usually a ruptured cerebral aneurysm) that rapidly fills the space between the brain and skull(subarachnoid space) with blood

sudden deficient supply of blood to the brain lasting a short time; symptons may be similar to stroke, but are temporary and the usual outcome is complete recovery.

gland that secretes adrenaline; located above each kidney

a chemical substance secreted by an endocrine gland that is carried by the blood to a target tissue

clusters of endocrine tissue found throughout the pancreas, made up of different cell types that secrete the hormone insulin

sum total of all the chemical processes that take place in a living organism

long organ that lies transversely across the upper abdomen that has a role in digestion as well as hormone secretion; contains the islets of Langerhans, which perform endocrine functions

pea-sized gland located under the hypothalamus near the brain; often called the master gland because it regulates many of the other glands

lymphatic organ located behind the sternum; produces T cells and secretes a hormone that supports the immune system

butterfly-shaped gland below the larynx on the front and sides of the trachea; secretes hormones that regulate the metabolism of carbohydrates, proteins, and fats

chronic syndrome resulting from a deficiency in the hormonal secretion of the adrenal cortex

chronic disease involving a disorder of carbohydrate metabolism caused by underactivity of the islets of Langerhans in the pancreas and resulting in insufficient production of insulin

a blood test to determine the amount of glucose in the blood after fasting for 8-10hrs

enlargement of the thyroid gland

a disorder of the thyroid gland characterized by the presence of hyperthyroidism, goiter, and exophthalmos (protusion of the eyes)
