Study Notes
General Veterinary Anatomy
- Anatomy is the science of form and structures of all organisms.
- Literally, the word means "to cut apart."
Aims of the Course
- Students gain knowledge of common veterinary anatomical terms and embryology.
- Students learn about the locomotor system of domestic animals.
- Students develop background on the origin and development of mammalian organisms, and the basic knowledge of general embryology.
- Students learn about congenital anomalies and morphological defects present at birth, as well as comparative anatomy of limb bones.
Classification of Anatomy
- There are 30 subdivisions of anatomy.
- Gross or macroscopic anatomy is based on dissecting animal cadavers. Structures visible to the naked eye are observed.
- General anatomy describes principles governing body structure.
- Special anatomy describes the structural features of specific species or organs.
- Comparative anatomy studies structures across animal species, focusing on characteristics aiding classification.
Classification of Anatomy (continued)
- Applied anatomy uses anatomical facts about living animals to improve clinical investigations, diagnoses, and surgical approaches.
- Instrumental anatomy uses specialized instruments like X-rays, CT scans, ultrasounds, and MRIs for diagnostic purposes.
- Embryology examines developmental anatomy from conception to birth.
- Morphology studies the form, position, and development of body structures (combining anatomy, histology, and developmental anatomy).
Methods for Approaching (Performing) Anatomy
- Systematic anatomy studies organs functioning in the same system.
- Topographical/regional anatomy investigates a specific body area, examining all structures within and their relationships. Regions include head, neck, trunk, forelimbs, and hindlimbs.
- Applied anatomy applies anatomical knowledge to living animals.
Nomenclatures of Body Systems
- Skeletal system: Osteology (bones).
- Articulation system: Arthrology (joints).
- Muscular system: Myology (muscles).
- Digestive system: Splanchnology (mouth, stomach, intestines).
- Respiratory system: Splanchnology (lungs, airways).
- Urinary system: Splanchnology (kidneys, urinary bladder).
- Reproductive system: Splanchnology (ovaries, testes, ducts).
- Endocrine system: Endocrinology (ductless glands).
- Nervous system: Neurology (brain, spinal cord, nerves).
- Circulatory system: Cardiology (heart, vessels).
- Sensory system: Esthesiology (eyes, ears).
- Common Integument: Dermatology (skin and associated structures).
Anatomical Terminology
- Terms are used to precisely describe position and direction of body parts. Anatomical terms apply to a four-legged animal in its typical standing position.
Body Planes
- Median/midsagittal/longitudinal plane divides the body into equal right and left halves.
- Sagittal/paramedian plane runs parallel to the median plane, in the head, body, or limbs.
- Transverse/segmental plane is perpendicular to the median plane, dividing into cranial and caudal segments.
- Frontal/horizontal/coronal plane is perpendicular to both the median and transverse planes, dividing into dorsal and ventral segments.
Anatomical Terms and Directions
- Rostral (toward the nose) is used in the head instead of cranial (toward the head).
- Cranial: toward the head.
- Caudal: toward the tail.
- Dorsal: toward the back.
- Ventral: toward the belly.
- Proximal: closer to the trunk.
- Distal: further from the trunk
- Axial: related to the longitudinal axis.
- Abaxial: away from the longitudinal axis.
- Superficial: close to the surface.
- Deep/internal: closer to the center.
- Medial: closer to the midline.
- Lateral: away from the midline.
Descriptive Terms of the Skeletal System
- Surfaces include eminences (projections), depressions (cavities), and foramina.
- Cavities/projections may be articular (for joints) or non-articular.
- Non-articular projections provide attachments for muscles, tendons, fascia, and ligaments.
Non-articular Projections
- Process: a general term for a prominence (e.g., spinous process of the scapula).
- Tuberosity: a large rounded projection (e.g., metacarpal tuberosity).
- Tubercle: similar to a tuberosity, but smaller.
- Trochanter: a prominent projection (e.g., trochanters of the femur).
- Spine/spinous process: a pointed projection (e.g., dorsal and ventral spines of vertebrae).
- Crest: a prominent ridge.
- Line: a small ridge (e.g., muscular lines of the subscapular fossa).
- Epicondyle: a projection near a condyle (e.g., epicondyle of the femur).
- Hamulus: a hook-like projection.
- Malleolus: a round projection (e.g., medial and lateral malleoli of the tibia).
Articular Projections
- Head: a rounded enlargement at the proximal end of a bone (e.g., head of humerus, femur).
- Condyle: a somewhat cylindrical articular eminence (e.g., condyles of the femur).
- Trochlea: a pulley-like articular surface (e.g., trochlea of the femur).
- Facet: a small, flat articular surface (e.g., costal facet of vertebrae).
Non-articular Depressions
- Fossa: a large, non-articular depression (e.g., supraspinous fossa of the scapula).
- Fovea: a small, non-articular depression (e.g., fovea capitis of the femur head).
- Groove/sulcus: a long, usually deep depression (e.g., musculospiral groove of the humerus).
- Foramen: a hole or opening (e.g., nutrient foramen).
- Fissure: a linear defect in a bone (or between two bones).
- Canal: a tunnel through one or more bones (e.g., vertebral canal).
- Meatus: a short canal (e.g., external acoustic meatus of the ear).
- Alveolus: a tooth socket.
Articular Depressions
Glenoid cavity: a shallow articular cavity (e.g., glenoid cavity of the scapula).
- Acetabulum/cotyloid cavity: a deep articular cavity (e.g., acetabulum of the pelvic bone).
- Notch: An articular depression (e.g., semilunar notch of the ulna).
Bones/Joints of Right Forelimb (Horse - Lateral View)
- Scapula (shoulder girdle)
- Humerus (arm region)
- Ulna and Radius (forearm)
- Carpus
- Metacarpus
- Phalanx (bones in the foot)
