Anatomy 4: Dissections Review

Comprehensive vocabulary flashcards covering human anatomy including the extremities, neck, head, thorax, and abdominal structures based on master-level dissection notes.

Tuberculum conoideum

A feature used to orient the clavicle, positioned laterally, inferiorly, and dorsally on the lateral half of the bone.

Labrum glenoidale

A fibrocartilaginous rim that borders the shallow cavitas glenoidalis to deepen the socket of the shoulder joint.

Sulcus nervi radialis

A groove found posteriorly on the corpus humeri, through which the radial nerve passes.

Rotator Cuff

A group of muscles that stabilize the shoulder joint, consisting of the m. subscapularis, m. supraspinatus, m. infraspinatus, and m. teres minor.

Plexus brachialis

A network of nerves formed by the anterior rami of C5 to T1, providing motor and sensory innervation to the arm muscles.

Mohrenheim-groef

Also known as the sulcus deltoideopectoralis, it is the pathway through which the v. cephalica travels in the shoulder region.

Membrana interossea

A fibrous sheet connecting the radius and ulna (or tibia and fibula), with fibers running laterally to medially in a downward direction.

Discus ulnocarpalis

The key fibrocartilaginous structure of the distal radio-ulnar joint.

Aponeurosis bicipitalis

A fibrous expansion of the biceps tendon that provides an indirect attachment to the ulna.

Flexor retinaculum

A structure forming the roof of the carpale tunnel, attaching to the os scaphoideum, os trapezium, os pisiforme, and os hamatum.

Canalis ulnaris

Also known as the Guyon tunnel, it is a superficial tunnel at the wrist containing the ulnar artery and ulnar nerve.

Musculi lumbricales manus

Four intrinsic hand muscles that flex the MCP joints and extend the IP joints, attaching to tendons rather than bone.

Arcus palmaris superficialis

A vascular arch in the hand formed primarily by the superficial branch of the ulnar artery anastomosing with the radial artery.

Acetabulum

The socket of the hip joint formed by the fusion of the os ilii, os ischii, and os pubis.

Linea terminalis

The pelvic brim that separates the pelvis major from the pelvis minor.

Ligamentum iliofemorale

Also known as the ligament of Bertini, it runs from the SIAI to the linea intertrochanterica to support the hip joint.

Hiatus adductorius

A gap between the two parts of the m. adductor magnus insertion that allows major blood vessels to pass from the front to the back of the thigh.

Vena saphena magna

A long superficial vein of the lower limb that starts at the ankle, runs medially at the knee, and ends at the v. femoralis.

Canalis adductorius

A passage between the vastus medialis and m. adductor longus, covered by the sartorius, through which femoral vessels travel.

Ligamentum arteriosum

A fibrous remnant of the fetal ductus arteriosus, connecting the pulmonary trunk to the aortic arch.

Circulus arteriosus cerebri

Also known as the Circle of Willis, it is an anastomosis of the carotis and vertebral systems that supplies blood to the brain.

Lobus insularis

The fifth, hidden lobe of the cerebral cortex located deep within the lateral sulcus.

Bulbus olfactorius

The structure where the first cranial nerve (n. olfactorius) synapses after passing through the lamina cribrosa.

Chiasma opticum

The X-shaped structure where optic nerve fibers from the two eyes meet and partially cross over.

Mediastinum

The central compartment of the thoracic cavity located between the two pleural cavities.

Valva tricuspidalis

The right atrioventricular valve, consisting of three cusps, that regulates blood flow from the right atrium to the right ventricle.

Sinus coronaris

The vessel on the dorsal side of the heart that collects most of the venous blood from the heart muscle and drains into the right atrium.

Hilum pulmonis

The depression on the medial surface of the lung through which bronchi, blood vessels, and nerves enter and exit.

Foramen epiploicum

Also known as the hiatus of Winslow, it is the opening that provides access to the bursa omentalis (lesser sac).

Teniae coli

Three distinct longitudinal bands of smooth muscle in the wall of the large intestine that help form haustra (bulges).

Porta hepatis

The transverse fissure on the visceral surface of the liver where the portal vein and hepatic artery enter and the hepatic ducts exit.

Glandula suprarenalis

Endocrine glands located within the capsula adiposa renalis superior to the kidneys.

M. levator ani

The primary muscle of the pelvic floor, composed of the m. iliococcygeus, m. pubococcygeus, and m. puborectalis.

Punctum nervosum

Also known as Erb’s point, a location on the posterior border of the sternocleidomastoid muscle where four superficial branches of the cervical plexus emerge.

Vagina carotica

The carotid sheath, containing the a. carotis communis, v. jugularis interna, and n. vagus.
