The fascial compartments of the neck Fig 188

Carotid Sheath

The fascial planes of the neck are of considerable importance to the surgeon they form convenient lines of cleavage through which he may separate the tissues in operative dissections and they delimit the spread of pus in neck infections. The superficial fascia is a thin fatty membrane enclosing the platysma. Pretracheal fascia containing thyroid, trachea, oesophagus and recurrent nerve Pretracheal fascia containing thyroid, trachea, oesophagus and recurrent nerve Carotid sheath containing...

The lymph nodes of the neck

Jugular Lymph Node

Although the lymph drainage of particular viscera is dealt with under appropriate headings tongue, larynx, etc. , it is convenient to summarize Fig. 219 Scheme of the lymph nodes of the head and neck. Superficial cervical along external jugular vein Deep cervical along internal jugular vein Superficial cervical along external jugular vein Deep cervical along internal jugular vein here the arrangements of the lymph nodes of the head and neck as a whole Fig. 219 . These can be grouped into...

The ulnar and radial bursae and the synovial tendon sheaths of the fingers Fig 146

Mid Palmar Space Infection

The flexor tendons traverse a fibro-osseous tunnel in each digit. This tunnel is made up posteriorly by the metacarpal head, the phalanges and the fronts of the intervening joints. The anterior fibrous part consists of condensed deep fascia attached to the sharp anterolateral margin of each phalanx and termed the fibrous flexor sheath. This is particularly tough over the phalanges but loose over the front of each joint it therefore holds the flexor tendons in place without 'bow-stringing'...

The prostatic capsules

Colliculus Seminalis

These are normally two, pathologically three, in number. 1 The true capsule a thin fibrous sheath which surrounds the gland. 2 The false capsule condensed extraperitoneal fascia which continues into the fascia surrounding the bladder and with the fascia of Denonvilliers posteriorly. Between layers 1 and 2 lies the prostatic venous plexus. 3 The pathological capsule when benign 'adenomatous' hypertrophy of the prostate takes place, the normal peripheral part of the gland becomes compressed into...
