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 |
