Superficial Muscles of the Back
Posterior view.
A Levator scapulae
S Rhomboideus major
D Serratus posterior inferior
F Lumbar triangle, internal oblique
G Thoracolumbar fascia, superficial layer
H Latissimus dorsi
J Scapular spine
K Trapezius, transverse part
Only the serratus posterior inferior is an intrinsic muscle of the back. The trapezius, latissimus dorsi, leva-tor scapulae, and rhomboideus muscles assist in move-ment of the shoulder or arm and are considered muscles of the upper limb.

Course of the Intercostal Nerves
Course of the Intercostal Nerves
Coronal section. Anterior view.
A Visceral pleura
S Parietal pleura, diaphragmatic part
D Diaphragm
F Costodiaphragmatic recess
G Endothoracic fascia
H External intercostal
J Costal groove
K Intercostal vein, artery, and nerve
Abnormal fluid collection in the pleural space (e.g., pleural effusion due to bronchial carcinoma) may necessitate the insertion of a chest tube. Generally, the optimal puncture site in a sitting patient is at the level of the 7th or 8th intercostal space on the posterior axillary line. The drain should always be introduced at the upper margin of a rib to avoid injuring the intercostal vein, artery, and nerve.

Right Lung
Lateral and medial views.
A Apex
S Horizontal fissure
D Middle lobe
F Oblique fissure
G Branches of right pulmonary artery
H Superior lobar bronchus
J Branches of right pulmonary veins
K Pulmonary ligament
Fig. 8.5A & C. From Atlas of Anatomy, p. 105.
The oblique and horizontal fissures divide the right lung into three lobes: superior, middle, and inferior. The apex of each lung extends into the root of the neck.

Kidneys & Ureters in Situ
What are the most common areas of constriction of the ureters?
Kidneys & Ureters in Situ
Male abdomen. Anterior view.
A Left suprarenal gland and vein
S Ureter (abdominal part)
D Psoas major
F Urinary bladder
G Right ductus deferens
H Right common iliac artery
J Right ovarian/testicular artery and vein
K Perirenal fat capsule
Constriction of the ureters occurs most often at one of three sites: where the renal pelvis narrows to become the ureter (ureteropelvic junction), where the ureter crosses the pelvic brim at the distal end of the common iliac vessels, and where it enters the bladder.

Superficial Veins of the Upper Limb

Superficial Veins of the Upper Limb
Right limb. Anterior, posterior views.
A Cephalic vein
S Basilic vein
D Median cubital vein
F Dorsal venous network
G Cephalic vein
The veins of the cubital fossa are frequently used when drawing blood. In preparation, a tourniquet is applied. This allows arterial blood to flow, but blocks the return of venous blood. The resulting swelling makes the veins more visible and palpable.

Lumbosacral Plexus II
What is the lumbosacral trunk?
Lumbosacral Plexus II
Right side. Anterior view.
A L1 vertebra
S Lumbosacral trunk
D Sciatic nerve
F Lateral femoral cutaneous nerve
G Femoral nerve
H Obturator nerve
J Ilioinguinal nerve
K Iliohypogastric nerve
The lumbosacral trunk refers to the nerve formed by anterior rami of L4 and L5 that descends into the pelvis to join the sacral plexus.

Lateral Cervical Topography I
What is the landmark in the neck known as Erb’s point?
Lateral Cervical Topography I
Right lateral view.
A External jugular vein
S Sternocleidomastoid
D Transverse cervical nerve
F Supraclavicular nerves
G Trapezius
H Great auricular nerve
J Lesser occipital nerve
Erb’s point is a landmark in the neck that refers to the approximate midpoint of the posterior border of the sternocleidomastoid muscle where the cutaneous nerves of the cervical plexus penetrate the deep cervical fascia.
