Regiones Abdominales * Regiones abdominales 1 - Regio epigastrica, 2 - Regio hypochondriaca, 3 - Regio umbilicalis, 4 - Regio lateralis, 5 - Regio pubica, 6 - Regio inguinalis. The regions of the stomach (Regiones abdominales) can be described with virtual lines: a vertical line through the middle of the Clavicula (medioclavicular line), a horizontal line halfway between the upper Sternum and the upper genital region (the horizontal layer is called Planum transpyloricum), and a horizontal line between the humps of the pelvic bone (Tuberculum iliacum) on both sides (the horizontal layer is called Planum intertuberculare). Regio epigastrica is located right under the Processus xiphoideus (at the bottom of Sternum) of the skeletal Thorax, marked by Planum transpyloricum at the bottom, and the medioclavicular lines on both sides. Regio hypochondriaca is located on both sides of Regio epigastrica, marked also by the Thorax, the medioclavicular line and Planum transpyloricum. Regio umbilicalis (the area around the belly) is marked by medioclavicular lines on both sides, by Planum transpyloricum at the top and Planum intertuberculare at the bottom. Regio lateralis is located on both sides of Regio umbilicalis, marked by Planum transpyloricum, Planum intertuberculare and medioclavicular lines on both sides. Regio pubica is located under the Regio umbilicalis, with a flowing transition into the lower located non-abdominal genital region (Regio urogenitalis). Regio inguinalis is located on both sides of Regio pubica. It is marked at the top by the Planum intertuberculare and the groin ligament (Ligamentum inguinale between the frontal upper spine of the pelvic bone= Spina iliaca anterior superior to the hump of the pubic bone= Tuberculum pubicum) at the bottom.

Regiones Capitis * Regiones capitis Reg. frontalis (1), Reg. orbitalis (2), Reg. nasalis (3), Reg. infraorbitalis (4), Reg. oralis (5), Reg. mentalis (6), Reg. buccalis (7), Reg. zygomatica (8), Reg. temporalis (9), Reg. parietalis (10), Reg. occipitalis (11)

Regiones Colli * Regiones Colli 1 - Regio sternocleidomastoidea, 2 - Trigonum submentale, 3 - Trigonum musculare, 4 - Trigonum submandibulare, 5 - Trigonum caroticum, 6 - Regio cervicalis lateralis.

Regiones Membri Inferioris 1 * Regiones membri inferioris (Aspectus anterior) 1 - Regio femoralis anterior, 2 - Trigonum femorale, 3 - Regio genus anterior, 4 - Regio cruralis anterior, 5 - Dorsum pedis, 6 - Digiti. The regions of the leg (Regiones membri inferioris) begin below Regio inguinalis on the front and below Regio lumbaris on the backside. The front side of the Femur (thigh) is called Regio femoralis anterior, the back side is covered by Regio glutaealis above the Musculus glutaeus maximus (origin at Os ilium, Os sacrum and Os coccygis= the coccyx; insertion at Femur and Tractus iliotibialis) and Regio femoralis posterior, divided by Sulcus glutaealis (bottom furrow). Regio femoralis anterior contains a region inside, called Trigonum femorale, marked by Musculus sartorius (origin at the frontal upper spine of the pelvic bone= Spina iliaca anterior superior; insertion at upper Tibia) and Musculus adductor longus (origin at the pubic bone= Os pubis; insertion at the back shaft of Femur bone= Linea aspera) at the sides and Regio inguinalis at the top. The area around the knee joint is called Regio genus (anterior and posterior). The lower leg (Crus) begins under this area, consisting of Regio cruralis anterior and posterior (the calf area is also called Sura or Regio suralis). The area of the heel is called Regio calcanea (Calx). The foot (Pes) can be divided into an upper area (Dorsum pedis), directed against the body, and a bottom area= the sole (Planta pedis), directed against the ground. Similar to the hands, the foot can be further divided into a Tarsus, Metatarsus and Digiti (Toes; I= Hallux, II= Digitus secundus, III= Digitus tertius, IV= Digitus quartus, V= Digitus minimus).

Regiones Membri Inferioris 2 * Regiones membri inferioris (Aspectus posterior) 1 - Regio glutaealis, 2 - Regio femoralis posterior, 3 - Regio genus posterior, 4 - Regio cruralis posterior= Reg. suralis, 5 - Regio calcanea, 6 - Planta pedis.

Regiones Pectorales * Regiones Pectorales 1 - Regio pectoralis, 2 - Regio praesternalis, 3 - Trigonum clavipectorale, 4 - Regio axillaris.

Skeleton * The Human Skeleton Bones form the skeleton, a protective and supportive framework, which has the following functions: The skeletal system protects and stabilizes inner structures like the thoracic organs (lungs, heart) or the brain. It acts as a lever to provide movement by muscular contractions and supports the body's upright posture, it produces blood cells in marrow (Haematopoiesis) and stores almost all of the body's calcium. The skeleton of an adult consists of 206 bones. This number must be seen as a variable because of possible variations in the number of the ribs, the sacral vertebrae or the sesamoid bones. Following the body axis, the skeleton may be divided into an axial skeleton, which consists of the bones of the skull, the hyoid bone, the vertebral column and the thoracic cage, and into an appendicular skeleton, consisting of the pectoral- and pelvic girdle and the bones of the upper- and lower limbs: - Axial skeleton: The bones of the Skull, Hyoid bone, the bones of the Vertebral column (Vertebrae), Sternum, Ribs - Appendicular skeleton: The Pelvic bone, Femur, Tibia, Fibula, bones of the Tarsus and Metatarsus, Phalanges, Humerus, Ulna, Radius, bones of the Carpus and Metacarpus

Standard Anatomic Position * Standard Anatomic Position of the Body In order to describe positions and orientations of the structures of the human body in three dimensions, the body is supposed to be in standing position, looking forward, arms at sides with palms of the hands pointing forward, and feet together pointing forward.

The Cell * The CellThis image presents the basic cellular structures. The nucleus contains the genetic material (DNA). It is responsible for the function and the replication of the cell. The mitochondria provide with their enzymes the cellular energy support. The are max. 6 micrometers long. The endoplasmatic reticulum builds proteins and enzymes, which are specific for the cellular function and excretion. The lysosomes are small digestive particles, which contain material to be sliced and eliminated. The cell membrane supports the cellular integrity and protects the cell from external alterations. It encapsulates the cytoplasma, which is the special fluid inside the cell. It bears the organelles and the nucleus.

Types of Bones * Types of Bones This image presents the most common types of bones. Based on shape, bones (Ossa) can be classified as follows: - Long bones (Ossa longa) are longer than they are wide. They are tubular in shape and have two ends. The long cylindrical body (Corpus, Diaphysis) consists of compact bone and has a central medullar cavity. The ends consist of spongy bone surrounded by a thin layer of compact bone. Typical long bones are the tubular bones of the limbs (Humerus, Radius, Ulna, Femur...). - Short bones (Ossa brevia) are cubical in shape. They consist of spongy bone covered by a thin layer of compact bone. Ossa brevia can be found in the wrist and ankle (Carpus and Tarsus). - Flat bones (Ossa plana) are thin and have broad surfaces. They are composed of two layers of compact bone tissue enclosing between them a variable quantity of cancellous bone (called Diploe in the skull bones). The Diploe can be locally absorbed and become pneumatic in some skull bones, forming inner bone cavities filled with air (Sinus). Such pneumatic skull bones are also called Ossa pneumatici. The flat bones are Os coxae (the hip bone), Scapula (shoulder blade), Sternum (breastbone), Costae (ribs), and some skull bones (Os frontale, Os occipitale, Os parietale…). - Irregular bones (Ossa irregularia) cannot be grouped into the upper categories because of their shape. They consist of spongy bone covered by a thin layer of compact bone. Irregular bones are the Vertebrae, Os sacrum, Mandibula, Os sphenoidale... - Sesamoid bones (Ossa sesamoidea) are a special type of bones which occur in tendons. A typical sesamoid bone is the Patella of the knee. According to some authors Patella can also belong to the group of short or flat bones.
