Introduction to Anatomy, Methods of Study, Topographic Terms & Nomenclatures

Flashcards covering introductory veterinary anatomy, historical figures, subdivisions of anatomy, systemic anatomy branches, planes of the body, directional terms, and regional anatomical nomenclature.

What are the Greek root words that form the word "Anatomy" and what do they mean?

"Ana" means apart, and "Tomy" means cut.

How is Anatomy defined, and by what primary methods is it studied?

Anatomy is the study of the structures of the body and the relation of its parts, usually studied by dissection and observation.

Who is recognized as the father of anatomy, and to what time period does his work date?

Aristotle is called the father of anatomy, dating back to at least the $4^{\text{th}}$ century B.C. when he published observations on the structures of fish and animals.

Besides anatomy, of what other biological disciplines is Aristotle considered the father?

Aristotle was also the father of comparative anatomy and physiology, and of later theories of evolution and embryology.

Who is considered the father of modern anatomy and when was he born?

Andreas Vesalius, a Belgian-born anatomist and physician born in $1514$ into a family of physicians, is considered the father of modern anatomy.

Who trained Leonardo da Vinci in anatomy?

Leonardo da Vinci was trained in anatomy by Andrea del Verrocchio.

What three basic facts of information does the study of anatomy involve?

The name, location or position, and function of the anatomic structures.

What is the difference between special anatomy and comparative anatomy?

Special anatomy studies specific species of animals (such as equine, ruminants, and carnivores), whereas comparative anatomy studies and compares anatomical structures in different species.

What is topographic anatomy, and what is a specific clinical example of it?

Topographic anatomy is the study of anatomical structures and functions of body organs related to surgery science, such as radiologic anatomy (x-ray anatomy).

Into what three branches is anatomy science divided according to the type of study?

$1.$ Gross or macroscopic anatomy (surface anatomy) $2.$ Microscopic anatomy (cellular anatomy) $3.$ Developmental anatomy or Embryological Anatomy

What subfields are included within gross or macroscopic anatomy?

Morphological, systemic, regional, and surgical anatomy.

How is developmental anatomy (embryological anatomy) defined?

The field of embryology concerned with the changes that cells, tissues, organs, and the body as a whole undergo from a germ cell of each parent to the resulting offspring.

What do osteology and arthrology (syndesmology) describe in systemic anatomy?

Osteology describes the bones and cartilages that form the body skeleton, while arthrology (syndesmology) describes the joints and ligaments of the body.

What do myology and splanchnology describe?

Myology describes the muscles and their tendons, while splanchnology describes the viscera (such as digestive, respiratory, and urogenital systems), endocrine glands, and peritoneum.

What structures are studied in angiology?

The heart, blood vessels (arteries and veins), and lymphatic vessels.

What do neurology, dermatology, and sensology describe?

Neurology describes the nervous system, dermatology describes the skin and related structures, and sensology describes the five basic senses related to the sensory system.

What is the general definition of an anatomical plane?

A surface, real or imaginary, along which any two points can be connected by a straight line.

How does the median plane differ from a sagittal plane?

The median plane longitudinally divides the head, neck, or trunk into two equal right and left halves, whereas a sagittal plane is parallel to the median plane and divides the trunk into two unequal parts.

What is a transverse plane?

A plane that is vertical or perpendicular to the median plane.

What directional term is used on the head in reference to the nose instead of cranial?

Rostral.

What are the directional meanings of cranial and caudal?

Cranial refers toward the head on the neck, trunk, and limbs proximal to the carpus and tarsus, while caudal refers relatively closer to the tail.

What does the directional term dorsal refer to, including its use on the limbs?

Relatively closer to the back (top) of the head, neck, trunk, or tail; on limbs, it is used instead of cranial on the manus and pes.

What is the definition of the directional term ventral?

Relatively closer to the underside of the head, neck, trunk, or tail.

Where and when are the terms palmar and plantar used?

Palmar is the supporting surface of the manus used instead of caudal or volar distally from the carpus; plantar is the supporting surface of the pes used instead of caudal or volar distally from the tarsus.

What do the directional terms medial and lateral indicate?

Medial means relatively closer to the median plane, while lateral means directed away from the median plane.

How do proximal and distal differ regarding the limbs?

Proximal is relatively closer to the trunk of the limbs, whereas distal is away from the trunk of the limbs.

What is the distinction between superficial and deep?

Superficial is near or relatively closer to the outer aspect of the body, while deep is near or relatively closer to the central aspect of the body.

What do the directional terms axial and abaxial mean?

Axial means relatively closer to the longitudinal axis of the limb, while abaxial means relatively further from the longitudinal axis of the limbs.

What do the positional terms prone and supine mean?

Prone means to lie face down in ventral recumbency, while supine means to lie face up in dorsal recumbency.

What does recumbent mean, and what are dorsal and ventral recumbency?

Recumbent describes the surface on which an animal is lying; dorsal recumbency means lying on the backbone, and ventral recumbency means lying on the ventral side (the tummy).

What anatomical regions are designated by brachial and antebrachium?

Brachial relates to the brachium region (the humerus bone and related muscles), while antebrachium relates to the radius and ulna and related muscles of the forelimb.

What is the distinction between axial and appendicular skeletal terms?

Axial relates to the skull and vertebral column, while appendicular relates to the forelimb and hindlimb.

What anatomical structures are indicated by crural, popliteal, and stifle?

Crural relates to the leg or hindlimb, popliteal relates to structures behind the knee region, and stifle refers to the knee joint in the hindlimb.

What do the anatomical terms perineal, peritoneal, and pleural describe?

Perineal describes the area between the vaginal opening and the back passage (anus), peritoneal relates to membranes covering internal organs, and pleural relates to the serous membrane in the thoracic cavity.
