VIVA Flashcards
Thoracic Muscles
subcostals,
transversus thoracis (laterally from sternum
Diaphragm
Innervation - Phrenic nerve C3-C5
Opening - Caval - T8 IVC
Oesophageal T10 - Oesophagus
Aortic Hiatus T12 - Aorta
Extrinsic Back Muscles
Superfical Move superolaterally: splenius, erector spinae (spinalis, longissimus, iliocostalis)
Intermediate move superomedially:
Semispinalis, multifidus, rotafores
Intrinsic Back Muscles
Move superiorly:
Interspinalis, intertransversari
Anatomy of Vertebrae
Vertebral foramen,
spinous process (bifid in cervical for ligament attachment),
transverse process,
superior and inferior articular facets, transverse foramen above C6 for vertebral artery
Vertebral Body
Vertebral Column segments
7 Cervical
12 Thoracic
5 Lumbar
5 Sacral
3-5 Coccygeal
Blood flow in heart
Right Atrium
Tricuspid valve
Right Ventricle
Pulmonary Valve
Pulmonary arteries
Lungs
Pulmonary Veins
Left Atrium
Bicuspid Valve
Left Ventricle
Aortic Valve
Ascending Aorta
Arch of Aorta
Descending Aorta
Abdominal Aorta
Vena Cava
Coronary Circulation
Out of aorta into the R & L coronary arteries. Right flows between atrium and ventricle. Left flows interventricularly. Left circumflex artery breaks off of left coronary and wraps posteriorly aswell as posterior descending artery.
Great cardiac vein follows the arteries
Nerve innervation of heart
Sympathetic - Cardiac Plexus T1-5
Parasympathetic - Vagus Nerve
Aortic Arch tributaries
Brachiocephalic trunk = Right common carotid & Right sublcavian
Left common carotid
Left subclavian
Left Lung
Superior and Inferior Lobes
Oblique fissure
Cardiac Notch
Right Lung
Superior, Middle, Inferior Lobes
Oblique fissure
Horizontal fissure
Abdominal Anatomy
Aorta - Bifurcates @ L4 into L & R iliac arteries
Duodenum - Superior mesenteric artery and vein go over
Kindeys –> Ureters
Pelvic Floor Anatomy
Levator Ani:
Pubococcygeus, iliococcygeus, Coccygeus, puborectalis
Mesentery
Mesentery is folds of peritoneum
Between the parietal and visceral layers of peritoneum is the peritoneal cavity which is serous, allowing for sliding.
Stomach rugae are inner folds that allow for expansion.
Lesser omentum connects the lesser curvature of the stomach to the superior liver.
Greater omentum connects the greater curvature of the stomach to the inferior large intestine.
