Physiology
Study of the function of living organisms
Ultrasound
Inaudible sound of high frequency used to outline various tissues and organs of the body.
Section
A cut through the body (or an organ)that is made along a particular plane; a thin slice of tissue prepared for microscopic study.
Midsagittal (median) plane
Specific sagittal plane that lies exactly in the midline.
Pleural cavities
A subdivision of the thoracic cavity; each houses a lung
Serous fluid
Clear, watery fluid secreted by cells of a serous membrane.
Cardiovascular system
Organ system which distributes the blood to deliver nutrients and remove wastes.
Vertebral (spinal) cavity
Body cavity that runs within the bony vertebral column; encloses the spinal cord.
Parasagittal planes
All sagittal planes offset from the midline.
Horizontal (transverse) plane
A plane running from right to left dividing the body into superior and inferior parts.
Ventral
Pertaining to the front; anterior.
Abdominopelvic cavity
Body cavity inferior to the thoracic cavity and separated from it by the diaphragm.
Dorsal body cavity
A large cavity within the axial portion of the body.
Peritoneum
Serous membrane lining the interior of the abdominal cavity and covering the surfaces of abdominal organs.
Ultrasonography
Use of ultrasound to produce an image of an organ or tissue.
Superior
Refers to the head or upper body regions.
Middle ear cavities
Contain tiny bones that transmit sound vibrations to the organ of hearing in the inner ears; medial to the eardrums.
Digestive System
System that processes food into absorbable units and eliminates indigestible wastes.
Endocrine system
Body system that includes internal organs that secrete hormones.
Frontal (coronal) plane
Longitudinal (vertical) plane that divides the body into anterior and posterior parts.
Integumentary system
Skin and its derivatives; provides the external protective covering of the body.
Embryology
Branch of developmental anatomy dealing with the changes that occur before birth.
Appendicular
Relating to the limbs; one of the two major divisions of the body.
Lymphatic system
System consisting of lymphatic vessels, lymph nodes, and other lymphoid organs and tissues; drains excess tissue fluid from the extracellular space and provides a site for immune surveillance.
Pelvic cavity
The inferior part of the abdominopelvic cavity; contains the bladder, some reproductive organs, and the rectum.
Sagittal plane
A longitudinal (vertical) plane that divides the body or any of its parts into right and left portions.
Superfical
Located close to or on the body surface.
Muscular system
The organ system consisting of the skeletal muscles of the body and their connective tissue attachments.
Cell
The structural and functional unit of living organisms; contains a nucleus and a variety of organelles enclosed by a limiting membrane.
Oblique section
A cut made diagonally between the horizontal and vertical plane of the body or an organ.
Gross (macroscopic) anatomy
Study of large body structures visible to the naked eye.
Parietal serosa
The part of the double-layered membrane that lines the walls of the ventral body cavity.
Synovial cavities
Joint cavities.
Organelles
Small cellular structures (ribosomes, mitochondria, and others) that perform specific metabolic functions for the cell as a whole.
Histology
Branch of anatomy dealing with the microscopic structure of tissues.
Oral cavity
Contains the teeth and tongue; commonly called the mouth.
Skeletal system
System of protection and support composed primarily of bone and cartilage.
Inferior (caudal)
Pertaining to a position near the tail end of the long axis of the body.
Organ system
A group of organs that work together to perform a vital body function; e.g., the nervous system.
Mediastinum
A subdivision of the thoracic cavity containing the pericardial cavity.
Pericardium
Double-layered serosa enclosing the heart and forming its superficial layer.
Surface anatomy
Study of internal body structures as they relate to the overlying skin surface.
Embryo
Developmental stage extending from gastrulation to the end of the eight week.
Anatomy
Study of the structure of living organisms.
Nervous system
Fast-acting control system that triggers muscle contraction or gland secretion.
Medial
Toward the midline of the body.
Reproductive system
Organ system that functions to produce offspring.
Respiratory system
Organ system that carries out gas exchange; includes the nose, pharynx, larynx, trachea, bronchi, lungs.
Pleura
Two-layered serous membrane that lines the thoracic cavity and covers the external surface of the lung.
Lateral
Away from the midline of the body.
Anterior
The front of an organism, organ, or part; the ventral surface.
Abdomen
Portion of the body between the diaphragm and the pelvis.
Regional anatomy
All the structures (muscles, bones, blood vessels, nerves, etc.) in one particular region of the body.
Abdominal cavity
Contains the stomach, intestines, spleen, liver, and other organs. It is inferior to the thoracic cavity and separated from it by the diaphragm.
Axial
Relating to the head, neck, and trunk; one of the two major divisions of the body.
Ventral body cavity
The more anterior and larger of the closed body cavities; contains the thoracic and abdominopelvic cavity.
Pharynx
Muscular tube extending from the region posterior to the nasal cavities to the esophagus.
Nasal cavity
Located within and posterior to the nose; is part of the respiratory system passageways.
Oragn
A part of the body formed of two or more tissues and adapted to carry out a specific function; e.g., the stomach.
Dorsal
Pertaining to the back; posterior.
Pericardial cavity
Located within the mediastinum of the thoracic cavity, it encloses the heart and also surrounds the remaining thoracic organs (esophagus, trachea, and others).
Visceral serosa
The part of the double-layered membrane that lines the outer surfaces of organs within the ventral body cavity.
Cranial cavity
Body cavity within which the brain is encased by the skull.
Thoracic cavity
The superior subdivision of the ventral body cavity, surrounded by the ribs and muscles of the chest.
