[Anatomy of the pelvic lymphatic system].

The lymphatic system of the pelvis collects the lymph of the genital and urinary organs and of the digestive tract. It is formed by lymphatic nodes and vessels situated inside the conjunctive tissue, near the organs (visceral lymphatic nodes) but especially along the external, internal and common iliac vessels (iliac lymphatic nodes). These nodes receive afferent vessels issued from the different pelvic organs.

Aim: To describe the anatomy and topography of the laryngeal fat body and of the space it lies within.

Materials And Methods: The study is carried out on series of histological sections of head and neck blocks from six foetuses and three newborns. Three adult necks were dissected, a fourth one analysed through sagittal median section.

Frohse's arcade is not the exclusive compression site of the radial nerve in its tunnel.

Introduction: The radial tunnel is a musculo-aponeurotic furrow which extends from the lateral epicondyle of humerus to the distal edge of the supinator muscle. The superficial head of the supinator muscle forms a fibrous arch, the arcade of Frohse (AF), which is the most common site of compression of the radial nerve motor branch. The latter is less commonly compressed by the adjacent muscular structures.

Relationships of the musculocutaneous nerve and the coracobrachialis during coracoid abutment procedure (Latarjet procedure).

Materials And Methods: Twenty-one embalmed adult trunks and upper limb were dissected. First the coracobrachialis and the musculocutaneous nerve were identified through a deltopectoral approach.

New findings on intermetacarpal fat pads: anatomy and imaging.

Many studies have focused on the functional importance of the gliding structures of the hand. These structures are clinically important in reconstructive surgery and mechanically essential for an efficient hand grasp. The aims of this study were to first review the intermetacarpal space and then focus on its fatty tissue, the intermetacarpal fat pad.

Microvascularisation of the male urethra in neonates and infants.

The microvascularisation of the male urethra was studied in neonates and infants by injection of agarised China ink into the circulation. The purpose of this study was to specify the angioarchitecture of each tunic of the urethral wall. The disposition of the microvascularisation networks varies depending on the urethral parts considered: only the mucous membrane networks are uniform throughout the entire urethra.

The lumbo-gluteal adipose body.

The lumbo-gluteal adipose body (LGAB) is a well-delineated fatty structure, in the lumbo-gluteal trigone, encroaching on the upper part of the gluteal region and flank. The aim of this study was to compare the gross and histological anatomy of the LGAB with that of other well-defined adipose bodies of the human body. The macroscopic study using dissections and slices in the main three planes in adults was supplemented by microscopic study of histological slices taken from fetuses and neonates.

Microvascularization of the female urethra in fetuses, neonates and infants.

The microvascularization of the female urethra was studied in fetuses, neonates and infants by injection of agarized China ink into the circulation. The purpose of this study was to specify the angioarchitecture of each tunic and their specific drainage. The disposition of the microvascularization of the urethra is superimposed on the orientation of the fibers of the muscular tunic.

Microvascularization of the mucocutaneous junction of the eyelid in fetuses and neonates.

The aim of this study was to specify the microvascularization of the junctional region between the integuments of the superficial surface of the free margin of the eyelid and the palpebral conjunctival mucosa. The study was carried out using histological or transparified slices of upper and lower eyelids taken from fetuses and neonates, in which the vascular system was injected with agarized China ink. The mucocutaneous junction of the eyelid is located at the posterior border of the free margin and extends to its deep surface.

Microvascularization of the mucocutaneous junction of the nose.

The aim of this study was to describe the microvascularization of the area of junction located between the integuments of the nasal ala and the respiratory mucosa. This study is part of an overall study on the microvascularization of the mucocutaneous junctions of the head. It was undertaken on histological or clarified sections of noses from fetuses, newborns and adults whose vascular system was injected with Indian ink agar.

Microvascularization of the mucocutaneous junctions of the head in fetuses and neonates.

The mucocutaneous junctions of the head (oral, nasal and palpebral) are transitional zones between the integuments and the mucosa. Their microvascularization is studied in the heads of fetuses and neonates by injection of agarized China ink into the vascular system. These zones are situated deep with respect to the free edge of the oral or nasal cavity or relative to the free margin of the eyelid.

Adipose body of the orbit.

The adipose body of the orbit (ABO) fills most of the orbital cavity, surrounding the eyeball, muscles, nerves, and vessels. It was studied in histologic section in the three basic planes in the fetus, neonate, and adult. In the retrobulbar area, that is, posterior to the eyeball, adipose tissue occupies the space around the optic nerve and penetrates between the recti muscles, describing a four-leafed clover pattern in frontal section.

Microvascularisation of lips in ageing edentulous subjects.

Macroscopic changes of the lips in the edentulous elderly subject are accompanied by variations in their microvascularisation. This study was undertaken on histological or clarified sections from totally edentulous subjects whose vascular system was injected with Indian ink agar. A reduction in density and size of the superficial (papillary or mucosal) and deep (reticular or submucosal) networks is observed with age.

Microvascularisation of the raphe buccalis in edentulous subjects, fetus, new-born and adult.

The aim of this study is to describe the microvascularisation of the raphe buccalis located at the inner surface of the cheek. The raphe buccalis is the zone where the maxillary and mandibulary prominences fuse in the embryo during the second month of life. This study was conducted using heads from edentulous subjects, fetuses, newborns and adults, injected with Indian ink in agar, then dissected or sectioned in the three basic planes.

Anatomy and imaging of the deep fat of the face.

The aim of this study is to investigate the deep adipose structures of the face.

Is the renal space closed?

The aim of this study is to verify the aperture or the closure of the renal space. The study is undertaken on histological sections of fetuses in the horizontal and sagittal planes. On each side, the kidney and the suprarenal gland are disposed in a space that is closed on all sides.

Microvascularisation of the lips in the fetus and neonate.

The differences observed in the microvascularisation of the lips in the perinatal period correspond to the differences in the histological structures of the cutaneous, glabra, intermediate cutaneous, villous, intermediate mucosal and mucosal parts. A basic pattern is found in each part: on the surface, a papillary or mucosal network, at a deeper level, reticular or submucosal networks and their pedicles. The vascular changes correspond to the transition of tissue (mucocutaneous junction) and are indicative of the functional aspect.

[Vascular architecture of the caudate nucleus].
