Breasts & Beyond

100

Dimpling/pitting of skin in this region (1) is the result of contraction/retraction of these structures (2)

(1) Mammory region/breast

(2) Suspensory ligament of Cooper

200

This lymph node initially receives all lymph from the breast and is often an indicator of metastasis

Sentinel Node

300

This group of lymph nodes receives lymph from most of the upper extremity

Humeral (lateral) group

400

A loose connective tissue plane between the breast and pectoral fascia

Retromammary space/bursa

500

Lateral mammary branches receive blood supply from this (1), which is a branch of the (2)

(1) Lateral thoracic artery

(2) Axillary artery

It's Nerves or Nothing

100

Injury to this nerve is caused by a surgical neck fracture or incorrect use of crutches

Axillary nerve

200

Ape thumb and the hand of benediction deformity are caused by injury to this nerve

Median nerve

300

Damage to this nerve causes weakened flexion of the elbow and supination of the forearm, and loss of sensation over the lateral aspect of the forearm

Musculocutaneous nerve

400

This reflex checks the radial nerve and its reflex center at C5-C6

Brachioradialis reflex

500

This nerve leaves the cubital fossa by passing between the 2 heads of the FCU  (1)

*BONUS* This artery follows deep to the 2 heads of the FCU

(1) Median nerve

(2) Ulnar artery

Brachial Plexus RIP

100

List the sections of the brachial plexus from proximal to distal (1), and the rami of the spinal nerves (2)

(1) Roots, Trunks, Divisions, Cords, Branches

(2) C5, C6, C7, C8, T1

200

This nerve/area is NOT numb after a brachial plexus block

Intercostobrachial nerve (T2)

300

This causes the inferior trunk of the brachial plexus to be compressed by the 1st rib

Postfixed brachial plexus

400

Erb-Duchenne palsy is caused by an injury to this part of the brachial plexus (1) and results in this sign (2)

(1) Superior part -> C5, C6

(2) Policeman's/Waiter's Tip hand

500

The name of the injury to the inferior part (C8, T1) of the brachial plexus

Klumpke's paralysis OR claw hand

Deformed for Days

100

Caused by excessive pressure due to bleeding from a fracture or swelling after a crush injury (1) and the procedure to resolve it (2)

(1) Compartment syndrome

(2) Fasciotomy

200

Deformity resulting from the distal interphalangeal joint suddenly being forced into extreme flexion

Mallet/Baseball finger

300

Deformity that results from the annular ligament becoming trapped between the radial head and the capitulum of the humerus

Nursemaid's/pulled elbow

400

This bone (1) is often fractured while using a racket, baseball bat, or golf club; it can cause injury to this nerve (2)

(1) Hamate

(2) Ulnar nerve

500

The Popeye sign is a clue that this tendon has ruptured

Tendon of the long head of biceps brachii

Embryo Part 1

100

When the fetus urinates, this occurs

The fetus swallows their urine and it is transported from fetal blood to maternal blood to be secreted

200

The name for the fine, soft, downy hair that covers a developing fetus in the womb

Lanugo

300

This is the function of the allantois

It is responsible for waste product removal from the fetus

400

These substances CAN cross the placenta

Gases (oxygen, CO2, CO)

Nutrients & electrolytes

Maternal antibodies

500

This occurs when the blastocyst implants close to/overlying internal os (isthmus) of the uterus and often results in late pregnancy bleeding

Placenta previa
