| Question | Answer |
|---|---|
| Aorta | Ascending, Arch, Descending |
| Brachiocephalic Artery | right side of arch, becomes right subclavian artery & Right Common Carotid |
| Left Common Carotid artery | left side of arch, splits into internal and external |
| Left Subclavian Artery | left side of arch , Vertebral Artery branches off of it |
| Right Common Carotid Artery | Branched off of Brachiocephalic, splits into internal & external |
| Vertebral Arteries | Arise off of Subclavians, within Transverse processes of cervicals, brings blood to brain |
| Veins | Take blood back to heart |
| Brachiocephalic Vein | Drains into Superior Vena Cava |
| Subclavian Vein | Drains into Brachiocephalic |
| Vertebral Veins | Drain into Subclavians |
| Jugular Vein (internal) | Drains into Brachiocephalic - In Anterior Triangle of neck |
| Jugular Vein (external) | Drains into Subclavian - posterior triangle of neck |
| Vagus Nerve CN X | innervates viscera, Major parasympathetic nerve in body |
| Phrenic nerve | Innervates diaphram |
| Anterior Triangle of neck | midline of neck, scm, mandible |
| posterior triangle of neck | SCM, Trapezius, Clavicle |
| Bony landmarks of anterior neck | 7 cervical vertebrae, Hyoid bone, Thyroid Cartilage, Cricoid Cartilage, Carotid Tubercle |
| Hypothalmus | controls and regulates pituitary |
| Oxytocin & ADH | hormones produced in hypothalmus & stored in (posterior) pituitary |
| Anterior pituitary | (Adenohypophysis) produces 7 hormones |
| Neurohypophysis | Posterior pituitary stores Oxytocin & ADH |
| Infundibulum | Connects pituitary & Hypothalmus |
| Thalmus | relay center for all sensory information going in/out of brain |
| pineal Gland | controls sleep cycle |
| Melatonin | hormone produced by pineal gland |
| Thyroid gland | produces T3, T4, Calcitonin |
| T3 & T 4 | produced by thyroid, regulate metabolism |
| Calcitonin | produced by thyroid gland maintains calcium homeostasis by lowering levels in blood |
| Parathyroid | located bleow thyroid, produces PTH |
| PTH | produced in Parathyroid, raises calcium blood levels |
| Antagonist to PTH | Calcitonin |
| Thymus Gland | located above heart, atrophies after puberty, assists in maturation of T cells |
| stems cell | immature cell |
| Adrenal glands | Suprarenal Glands |
| Cortex of Adrenals | produce Glucocorticoids, cortisol, mineralcorticoids, aldosterone, androgens |
| Cortisol | Anti-inflamitory produced by Adrenal Glands |
| Mineralcorticoids, Aldosterone | produced by adrenals, hold sodium & prevent dehydration |
| Androgens | produced by adrenals, form male/female sex characteristics |
| Medulla of Adrenals | produce Epinephrine or adrenaline |
| Epinephrine | Also called adrenaline, produced by medulla of Adrenals |
