Flashcards in Anatomy Deck (33):
1

Direct inguinal hernia

Protrudes through abdominal wall through Hasselbach's triangle, medial to inferior epigastric vessels, through superficial ring. More common in older men.

2

Indirect inguinal hernia

Protrudes through abdominal wall lateral to inferior epigastric vessels (lateral to triangle) and goes through both superficial and deep rings and into the scrotum. Occurs due to failure of the processus vaginalis to close.

3

Inguinal triangle

Made up of rectus abdominus medially, inguinal ligament inferolaterally, and inferior epigastric vessels superolaterally

4

Functions of musculocutaneous nerve

Innervates biceps. Sensation to lateral forearm.

5

Innervation for erection

Parasympathetics of S2-S4, which also innervates anal and penile sensation.

6

Orther syndrome

Compression of right recurrent laryngeal nerve by enlarged left atrium.

7

Relationship between internal jugular vein and common carotid artery

IJV lateral to common carotid

8

Cause of congenital diaphragmatic hernia

Failure of pleuroperitoneal canal to close completely

9

Right dominant circulation

RCA gives off posterior descending artery

10

Nerve damaged in fracture of surgical neck of humerus

Axillary nerve

11

Blood supply to pancreas

Branches of SMA and gastroduodenal artery

12

Layers of epidermis (bottom to top with function)

Stratum basalis: generates keratinocytes, rapidly divides, where melanocytes live
Stratum spinosum: desmosomes, langerhans immune cells
Stratum granulosum: keratohyalin granules, releases lamellar bodies to form the waterproof lipid layer of skin
Stratum lucidum: clear layer of dead keratinocytes without nuclei
Stratum corneum: layers of flat dead keratinocytes that slough

13

Nerves associated with cribriform plate

CNI

14

Nerve and vessel associated with optic canal

CNII, opthalmic artery

15

Nerves and vessels associated with superior orbital fissure

CNIII, IV, V1, VI, superior opthalmic veins

16

Nerve associated with foramen rotundum

V2

17

Nerve associated with foramen ovale

V3

18

Vessels associated with foramen spinosum

Middle meningeal artery and vein

19

Nerves associated with internal auditory meatus

VII and VIII

20

Nerves associated with jugular foramen

IX, X, XI

21

Nervs associated with hypoglossal canal

XII

22

Nerves associated with foramen magnum

Vertebral artery

23

Nerves associated with stylomastoid foramen

VII

24

Cardinal ligaments

At base of broad ligaments. Contain uterine arteries and veins.

25

Meissner's vs pacini corpuscles

Meissners: light touch
Pacini: vibration, course touch, pressure

26

Right lymphatic duct

Drains right chest, back, arm, neck, head. Empties into angle between internal jugular and subclavian veins.

27

Neurofibromatosis type 2

Classically presents with bilateral acoustic neuromas. Optic gliomas and juvenile cataracts also classic findings. Caused by mutation of tumor suppressor gene merlin on chromosome 22.

28

Neurologic findings of vitamin B12 deficiency

Degeneration of neurons and myelin in dorsal columns, lateral corticospinal tract, and spinocerebellar tracts lead to dementia-like symptoms and ataxia

29

Result of straddle injury

Can cause rupture of urethra below urogenital diaphragm. Causes urine to flow into scrotum and perineal region.

30

Yolk sac tumor of testis

Peak incidence in infancy and early childhood. Elevated alpha fetoprotein. Lump in testicle + pain.

31

Suspensory ligament of ovary

Contain ovarian arteries and viens

32

Tensor typmpani

Muscle that pulls tympanic membrane medially, increasing tension on it. Innervated by V3.

33

Anatomy of bronchopulmonary segments

Supplied by tertiary bronchus, bronchial artery, and pulmonary partery which run together in center of segments. Veins and lymphatics drain together along edges of segments.
