ATTACHMENTS OF CHEST MUSCLES[edit | edit source]
- A lady between two majors.
- Pectoralis major attaches to lateral lip of bicipital groove.
- Teres major attaches to medial lip of bicipital groove.
- Latissimus dorsi attaches to the floor of bicipital groove.
- The "lati" is between two "majors."
- "Lateral is less, medial is more."
- Lateral pectoral nerves goes through pectoralis major while medial pectoral nerve goes though both pectoralis major and minor
CRANIAL NERVES[edit | edit source]
I - olfactory, II - optic, III - oculomotor, IV - trochlear, V - trigeminal, VI - abducens, VII - facial, VIII - acoustic (vestibulocochlear), IX - glossophrayngeal, X - vagus, XI - accessory, XII - hypoglossal

Deep Reflexes[edit | edit source]
Biceps (C5-6) elbow flexion
Brachio-radialis (C5-6) elbow flexion & supination
Triceps (C7) elbow extension
Patellar (L3-4) knee extension = knee jerk
Achilles (S1) plantar flexion = ankle jerk
LR6 SO4 R3[edit | edit source]
- LR6 - Lateral Rectus --> CN VI Abducens
- SO4 - Superior Oblique --> CN IV Trochlear
- R3 - The Remaining 4 eyeball movers --> CN III Occulomotor
- or LAST: LA = Lateral Rectus - Abducens Nerve, ST = Superior Oblique - Trochlear Nerve
BRANCHES OF FACIAL NERVE[edit | edit source]

CERVICAL SPINAL NERVES[edit | edit source]
- c345 keep the diaphragm alive (innervation of diaphragm by the phrenic nerve)
- c5-6-7 raise your arms to heaven (nerve roots of long thoracic nerve innervate serratus anterior and if severed you see "winging" of the scapula)
INNERVATION OF PENIS[edit | edit source]
- Parasympathetic causes erection. Sympathetic causes ejaculation. "Point and Shoot."
- "S2, 3, 4 keep the penis off the floor"
- Innervation of the penis by branches of the pudendal nerve, derived from spinal cord levels S2-4
AORTIC BRANCHES[edit | edit source]
- Aortic arch gives off the Brachiocephalic trunk, the left Common Carotid, and the left Subclavian artery
Order of things in the Femoral Triangle[edit | edit source]
- "N(AVEL)" (From Lateral To Medial)
- Nerve, Artery, Vein, Empty space, Lymphatics
NOTE: Parenthesis includes things contained in the femoral sheath.
LOCATION OF INQUINAL HERNIAS with Reference to the Inferior Epigastric Arteries:
- "MDs don't LIe" (Medial- Direct, Lateral - Indirect): Direct inquinal hernias are Medial while Indirect hernias are Lateral to the inferior epigastric arteries
