Study Notes

Anatomy and Physiology Study Notes

Calcaneus and Talus Articulation: The three articular surfaces of the calcaneus that join with the talus are the anterior facet, lateral facet, and posterior facet. Only the anterior and lateral facets are involved in the joint.
Rotator Cuff Muscle Insertion: The supraspinatus inserts onto the greater tubercle anteriorly, the infraspinatus & teres minor onto the posterior aspect of the greater tubercle, and the subscapularis onto the lesser tubercle.
Lambdoid Suture: The lambdoid suture forms the joint between the parietal and occipital bones situated posterior to the coronal suture.
Sagittal Plane: A vertical plane that divides the body into right and left halves.
Total Lung Capacity (Male): The approximate total lung capacity in a healthy adult male is 6000 mL.
Elbow Fat Pads: The three fat pads associated with the elbow are the pronator fat pad, supinator fat pad, and posterior fat pad.
Right Coronary Artery Branches: The right marginal artery is a branch of the right coronary artery.
Esophageal Compression: The esophagus can be compressed by the aortic arch, right main bronchus, but not the left vagus or right brachiocephalic vein.
Gas Exchange in Lungs: Gas exchange occurs within the alveoli of the lungs.
Gallbladder Capacity: The maximum capacity of the gallbladder for storing bile is approximately 70 mL.
Glomerular Capsule Filtration: Approximately 180 L of filtrate enters the glomerular capsule each day.
Kidney Filtration Apparatus: The glomerular capsule acts as the filtration apparatus of the kidneys.
Anterior Interventricular Artery: The anterior interventricular artery is a branch of the left coronary artery.
Cardiac Cycle Valves: During ejection, the atrioventricular valves are closed, while the semilunar valves are open.
Air Passage from Bronchi: The correct order for air passing through the structures after the bronchi are: terminal bronchioles, respiratory bronchioles, alveolar ducts, alveoli.
Meninges: The three connective tissue membranes protecting the CNS structures are collectively known as the meninges.
Spongy Bone in Long Bones: In a typical long bone, spongy bone is found within the epiphyses.
Bone Communication Canals: Volkmann's (perforating) canals communicate from the outside of the bone to its interior central canals.
Substances Not Through Glomerular Capsule: Glucose does not normally pass through the glomerular capsule.
Lungs Serous Membrane: The serous membrane on the surface of the lungs is called visceral pleura.
Blood Delivery to Left Atrium: Blood is delivered to the left atrium by the pulmonary veins.
Directional Terms: Body planes, sections or directions.
Posterior Mediastinum Structures: The azygos vein is in the posterior mediastinum.
Duodenojejunal Junction Support: The duodenojejunal junction is supported by the ligament of Treitz.
Pancreatic and Bile Duct Union: The pancreatic duct and bile duct unite to form the hepatopancreatic ampulla.
Renal Hilum Parts: The renal vein is anterior to the renal artery, which is anterior to the renal pelvis; the renal hilum is on the concave medial margin of the kidney.
Chief Muscle of Inspiration: The diaphragm is the chief muscle of inspiration.
Aorta Bifurcation Location: The abdominal aorta bifurcates at the level of the diaphragm.
Crest of the Ilium: The crest of the ilium is a bony anatomical feature.
Digestion Location: Digestion primarily takes place in the stomach and duodenum.
Water Reabsorption: Most water reabsorption occurs primarily in the jejunum.
Pelvic Inlet Boundaries: The pelvic inlet is not defined by the inferior ramus of the pubis.
Uterine Part Entering Vagina: The fundus portion of the uterus protrudes into the upper most vagina.
Male Accessory Gland: The largest accessory gland in the male reproductive system is the prostate.
Kyphosis: Kyphosis can result from developmental anomalies and osteoporosis.
Shoulder Joint Injury: The shoulder is the most frequently injured major joint.
Nasal Conchae: Inferior nasal concha is a separate bone on its own.
Lambdoid Landmark: The lambda is a landmark where the sagittal and lambdoid sutures meet.
Landmark Between C1 and C2: There is no intervertebral disc between C1 and C2 vertebrae.
Vertebral Column Functions: The vertebral column supports the body, protects the spinal cord, plays a role in posture and movement.
Hip Injury: It is not a case separate bone.
Scoliosis Causes: Differences in length of the upper limbs, or asymmetrical weakness of intrinsic back muscles
Humerus Condyle: The radial, coronoid, and olecranon fossae, trochlea, and capitulum are part of the humerus condyle.
**Wrist joint ** carpometacarpal and intermetacarpal joints are plane type of synovial joints except for the carpometacarpal joints of the thumb and the 5th metacarpal.
External and Internal Layers of the pericardium: The external layer of the sac of the pericardium is the fibrous pericardium and the internal layer is the visceral layer of the pericardium which is called the epicardium .
