Applicable Clinical Terms Definitions

Abdominal Wall: The outer margins of the ABDOMEN, extending from the osteocartilaginous thoracic cage to the PELVIS. Though its major part is muscular, the abdominal wall consists of at least seven layers: the SKIN, subcutaneous fat, deep FASCIA; ABDOMINAL MUSCLES, transversalis fascia, extraperitoneal fat, and the parietal PERITONEUM.

Alveolar Process: The thickest and spongiest part of the maxilla and mandible hollowed out into deep cavities for the teeth.

Ankle: The region of the lower limb between the FOOT and the LEG.

Axilla: Area of the human body underneath the SHOULDER JOINT, also known as the armpit or underarm.

Breast: In humans, one of the paired regions in the anterior portion of the THORAX. The breasts consist of the MAMMARY GLANDS, the SKIN, the MUSCLES, the ADIPOSE TISSUE, and the CONNECTIVE TISSUES.

Cheek: The part of the face that is below the eye and to the side of the nose and mouth.

Chin: The anatomical frontal portion of the mandible, also known as the mentum, that contains the line of fusion of the two separate halves of the mandible (symphysis menti). This line of fusion divides inferiorly to enclose a triangular area called the mental protuberance. On each side, inferior to the second premolar tooth, is the mental foramen for the passage of blood vessels and a nerve.

Ear: The hearing and equilibrium system of the body. It consists of three parts: the EXTERNAL EAR, the MIDDLE EAR, and the INNER EAR. Sound waves are transmitted through this organ where vibration is transduced to nerve signals that pass through the ACOUSTIC NERVE to the CENTRAL NERVOUS SYSTEM. The inner ear also contains the vestibular organ that maintains equilibrium by transducing signals to the VESTIBULAR NERVE.

Elbow: Region of the body immediately surrounding and including the ELBOW JOINT.

Epiglottis: A thin leaf-shaped cartilage that is covered with LARYNGEAL MUCOSA and situated posterior to the root of the tongue and HYOID BONE. During swallowing, the epiglottis folds back over the larynx inlet thus prevents foods from entering the airway.

Eyelids: Each of the upper and lower folds of SKIN which cover the EYE when closed.

Face: The anterior portion of the head that includes the skin, muscles, and structures of the forehead, eyes, nose, mouth, cheeks, and jaw.

Fever: An abnormal elevation of body temperature, usually as a result of a pathologic process.

Forearm: Part of the upper extremity in humans and primates extending from the ELBOW to the WRIST.

Forehead: The part of the face above the eyes.

Gingiva: Oral tissue surrounding and attached to TEETH.

Hand: The distal part of the arm beyond the wrist in humans and primates, that includes the palm, fingers, and thumb.

Head: The upper part of the human body, or the front or upper part of the body of an animal, typically separated from the rest of the body by a neck, and containing the brain, mouth, and sense organs.

Heel: The back (or posterior) of the foot in PRIMATES, found behind the ankle and distal to the toes.

Hip: The projecting part on each side of the body, formed by the side of the pelvis and the top portion of the femur.

Jaw: Bony structure of the mouth that holds the teeth. It consists of the MANDIBLE and the MAXILLA.

Knee: A region of the lower extremity immediately surrounding and including the KNEE JOINT.

Larynx: A tubular organ of VOICE production. It is located in the anterior neck, superior to the TRACHEA and inferior to the tongue and HYOID BONE.

Lip: Either of the two fleshy, full-blooded margins of the mouth.

Mouth: The oval-shaped oral cavity located at the apex of the digestive tract and consisting of two parts: the vestibule and the oral cavity proper.

Nails: The thin, horny plates that cover the dorsal surfaces of the distal phalanges of the fingers and toes of primates.

Neck: The part of a human or animal body connecting the HEAD to the rest of the body.

Nose: A part of the upper respiratory tract. It contains the organ of SMELL. The term includes the external nose, the nasal cavity, and the PARANASAL SINUSES.

Palate: The structure that forms the roof of the mouth. It consists of the anterior hard palate (PALATE, HARD) and the posterior soft palate (PALATE, SOFT).

Pelvis: The space or compartment surrounded by the pelvic girdle (bony pelvis). It is subdivided into the greater pelvis and LESSER PELVIS. The pelvic girdle is formed by the PELVIC BONES and SACRUM.

Penis: The external reproductive organ of males. It is composed of a mass of erectile tissue enclosed in three cylindrical fibrous compartments. Two of the three compartments, the corpus cavernosa, are placed side-by-side along the upper part of the organ. The third compartment below, the corpus spongiosum, houses the urethra.

Pharynx: A funnel-shaped fibromuscular tube that conducts food to the ESOPHAGUS, and air to the LARYNX and LUNGS. It is located posterior to the NASAL CAVITY; ORAL CAVITY; and LARYNX, and extends from the SKULL BASE to the inferior border of the CRICOID CARTILAGE anteriorly and to the inferior border of the C6 vertebra posteriorly. It is divided into the NASOPHARYNX; OROPHARYNX; and HYPOPHARYNX (laryngopharynx).

Scalp: The outer covering of the calvaria. It is composed of several layers: SKIN; subcutaneous connective tissue; the occipitofrontal muscle which includes the tendinous galea aponeurotica; loose connective tissue; and the pericranium (the PERIOSTEUM of the SKULL).

Scrotum: A cutaneous pouch of skin containing the testicles and spermatic cords.

Shoulder: Part of the body in humans and primates where the arms connect to the trunk. The shoulder has five joints; ACROMIOCLAVICULAR joint, CORACOCLAVICULAR joint, GLENOHUMERAL joint, scapulathoracic joint, and STERNOCLAVICULAR joint.

Testis: The male gonad containing two functional parts: the SEMINIFEROUS TUBULES for the production and transport of male germ cells (SPERMATOGENESIS) and the interstitial compartment containing LEYDIG CELLS that produce ANDROGENS.

Thigh: The superior part of the lower extremity between the HIP and the KNEE.

Thumb: The first digit on the radial side of the hand which in humans lies opposite the other four.

Tongue: A muscular organ in the mouth that is covered with pink tissue called mucosa, tiny bumps called papillae, and thousands of taste buds. The tongue is anchored to the mouth and is vital for chewing, swallowing, and for speech.

Trachea: The cartilaginous and membranous tube descending from the larynx and branching into the right and left main bronchi.

Arm: The superior part of the upper extremity between the SHOULDER and the ELBOW.

Uvula: A fleshy extension at the back of the soft palate that hangs above the opening of the throat.

Vagina: The genital canal in the female, extending from the UTERUS to the VULVA. (Stedman, 25th ed)

Vocal Cords: A pair of cone-shaped elastic mucous membrane projecting from the laryngeal wall and forming a narrow slit between them. Each contains a thickened free edge (vocal ligament) extending from the THYROID CARTILAGE to the ARYTENOID CARTILAGE, and a VOCAL MUSCLE that shortens or relaxes the vocal cord to control sound production.

Vulva: The external genitalia of the female. It includes the CLITORIS, the labia, the vestibule, and its glands.

Wrist: The region of the upper limb between the metacarpus and the FOREARM.
