    Medical and Anatomy Quiz Review

    • Thyroid Stimulating Hormone (TSH): Target organ is the Thyroid; function is production of T3 and T4.
    • Prolactin: Target organ is the Breast; function is milk production.
    • Parathyroid Hormone: Function: increases plasma calcium levels.
    • Brain Stem Components: The thalamus is not part of the brain stem.
    • Rib Classification: Floating ribs do not attach to costal cartilage.
    • "Sugar, Salt, and Sex" Mnemonic: Refers to Cortisol, Aldosterone, and Testosterone.
    • Passive Membrane Transport: Example is osmosis.
    • Cranial Nerve I (Olfactory Nerve): Function: Sense of smell.
    • Leg Bones: The tibia and fibula.
    • Hypothalamus: Not part of the Midbrain.
    • Hormones and Their Glands: Glucagon, PTH and TSH are secreted by the pancreas, parathyroid, and anterior pituitary, respectively.
    • Posterior Pituitary Gland: Another name is the neurohypophysis.
    • Bone Cells: Osteoclasts are bone-reabsorbing cells.
    • Accumulation of CSF: This condition is known as hydrocephalus.
    • Hematopoiesis: Occurs in red bone marrow.
    • Norepinephrine Releasing Axon: The sympathetic axon.
    • Cranial Nerve XI: Corresponds to the accessory nerve.
    • True Ribs: Ribs attached individually to the sternum by cartilage.
    • Insulin Function: Secreted by beta cells of the islets of Langerhans.
    • Nervous System Divisions: Peripheral and Central Nervous System.
    • Cervical Vertebrae Count: 7 cervical vertebrae.
    • Insulin and Glucagon: Function in regulating blood glucose.
    • Growth Hormone (GH): Target organ/function is for growth.
    • Aldosterone Function: Also known as "salt-retaining hormone".
    • Eye Movement Nerves: The optic nerve is not involved in eye movement.
    • Long Bone Anatomy: The hollow shaft is called the diaphysis.
    • Forearm Bones: The ulna and radius.
    • Skin Layer with Melanocytes: Melanocytes are located in the epidermis.
    • Brain Stem and Vital Centers: The medulla oblongata is part of the brain stem involved in vital functions like breathing and heart rate.
    • Brain Coordination: The cerebellum coordinates equilibrium.
    • Somatotropic Hormone (GH): Stimulates skeletal muscle and bone growth.
    • Somatic and Parasympathetic Neurotransmitter: Acetylcholine.
    • Growth Hormone (GH) Functions: Stimulates musculoskeletal growth; secreted by adenohypophysis.
    • Parathyroid Hormone (PTH) Function: Activates osteoclasts.
    • Hormones Secreted by the Posterior Pituitary: Oxytocin.
    • Iodine Use in the Body: Necessary for thyroid hormone production.
    • Cerebral White Matter: Heavily myelinated part of the cerebrum is called white matter.
    • Antidiuretic Hormone (ADH): Reduces urine excretion.
    • Opposing Function of Calcitonin: Parathyroid Hormone (PTH).
    • Oxytocin Function: Target organ/function is for milk ejection.
    • Catecholamines: Include epinephrine and norepinephrine.
    • Adrenaline (Epinephrine) Effect on Alpha-1 Receptors: Vasoconstriction.
    • Cranial Nerve II: Corresponds to the optic nerve.
    • Calcitonin Secretion: Elevated plasma calcium levels trigger its release.
