Pars Nervosa

The tissue that constitutes the neurohypophysis (posterior pituitary)

Pars Intermedia

The tissue that separates the two lobes of the hypophysis (pituitary)

Pars Distalis

The tissue that constitutes the adenohypophysis (anterior pituitary)

Follicular Cells of Thyroid

Simple cuboidal epithelium; secretes thyroid hormone

Parafollicular Cells of Thyroid

Cells that are located between the follicles; synthesize, secrete, and store calcitonin

Thyroid Colloid

Thick fluid that fills the interior of thyroid follicles; made of tyrosine; stores thyroid hormone

Chief Cells (Principal Cells)

Cells that produce parathyroid hormone

Zona Glomerulosa

Outermost of layer of adrenal cortex; produces mineralcorticoids (mainly aldosterone)

Zona Fasciculata

Middle layer of adrenal cortex; produces glucocorticoids

Zona Reticularis

Deepest layer of adrenal cortex; produces gonadocortioids

Adrenal Medulla

Deepest layer of adrenal gland; produces epinephrine and norepinephrine

Acini

Cells that secrete enzymes in the pancreas for digestion

Sertoli Cells (Nurse Cells)

Cells that produce sperm

Leydig Cells

Cells that produce testosterone

Ovarian Follicle

Fluid filled sac that contains an immature egg

Pineal Gland

Gland that secretes melatonin

Hypophysis (Pituitary Gland)

Gland that secretes growth and reproduction hormones as well as neurotransmitters

Hypothalamus

The "overlord"; coordinates autonomic nervous system and hypophysis (pituitary) function

Thymus

Gland in the thoracic cavity above the heart where T lymphocytes mature

Thyroid

Gland that produces hormones that regulate metabolism, body heat, and bone growth

Parathyroid Glands

Gland(s) that produces parathyroid hormone

Adrenal Glands

Gland(s) that produces adrenocortical steroids

Testes

Organ(s) that produces testosterone and sperm

Ovaries

Organ(s) that produces estrogen & progesterone as well as eggs

Kidneys

Organ(s) that secrete calcitriol, erythropoietin, and renin

Spleen

Organ near the stomach that produces, stores, and eliminates blood cells

Erythrocytes

Cells that transport oxygen and carbon dioxide in the blood stream

Neutrophils

First responder; engulfs invading pathogens

Eosinophils

Increased in allergic reactions and parasitic infections; reduces inflammation at injury site.

Basophils

Produces histamine and heparin; rarest white blood cell

Monocytes

2x as big as RBC's. Becomes macrophages; engulfs pathogens, old cells, and any other debris. Stimulates other white blood cells.

Lymphocytes

3 Types:
B cells - produce antibodies
T cells - destroy cells with antigens
NK cells - fight cancer

Thrombocytes

Cells that transport chemicals for clotting process; form temporary patches in damaged blood vessel walls

Sickle Cell

An abnormal RBC that is crescent shaped and produces abnormal hemoglobin - this prevents it from transporting gasses efficiently.
