| Term | Definition |
|---|---|
| Cranial cavity | The space within the skull that houses and protects the brain. This cavity is part of the dorsal body cavity system. |
| Deep | Positioned farther from the body surface, toward the interior. These structures are located internally relative to superficial structures. |
| Diaphragm | The large muscle that separates the thoracic and abdominal cavities and is essential for breathing. The muscle contracts and relaxes to change chest cavity pressure for respiration. |
| Distal | Father away from the body's center or point of attachment. On limbs, xxxx structures are farther from where the limb attaches to the body. |
| Dorsal | Toward the back or upper surface of the body. In standing animals, xxxx refers to the spine side of the body. |
| Dorsal body cavity | The body cavity that contains the central nervous system, including the cranial cavity (brain) and the spinal cavity (spinal cord). |
| Dorsal plane | An imaginary horizontal plane that divides the body into xxxx (back) and xxxxx (belly) portions. |
| Dorsopalmar view | A radiographic projection where the X-ray beam travels from the back to the palm surface of the front limb below the carpus. |
| Epithelial tissue | Tissue that covers body surfaces and lines body cavities, providing protection and sometimes absorption. These tightly packed cells from barriers against the environment. |
| Fetlock | The joint in a horse's leg located between the cannon bone and the pastern, similar to the knuckle in humans. |
| Flank | The side region of a horse between the last rib and the hip. This area corresponds to part of the abdominal wall. |
| Homeostasis | The body's ability to maintain stable internal conditions despite external changes. This involves coordinated responses from multiple body systems to keep temperature, pH, and fluid balance with normal ranges. |
| Hock | The joint in the middle of a horse's hind leg. equivalent to the human ankle. This complex joint allows for movement and weight bearing. |
| Knee | The joint in the middle of a horse's front leg, equivalent to the human wrist (carpus). |
| Lateral | Toward the side of the body, away from the midline. Structures positioned farther from the center line are described as xxxx. |
| Lateral view | A radiographic projection taken from the side of the animal, were the X-ray beam enters one side and exits the other. |
| Macroscopic | Large enough to be seen with the naked eye, without magnification. Refers to structures visible during regular examination or gross anatomy study. |
| Median plane | The imaginary plane that divides the body into equal left and right halves, running down the exact center from head to tail. |
| Medial | Toward the midline or center of the body. Structures positioned closer to the median plane are described as xxxxx. |
| Microscopic | Too small to be seen without magnification, requiring a microscope for visualization. Refers to cellular and subcellular structures. |
| Muzzle | The nose and mouth area of an animal, including the nostrils and lips. This region contains important sensory structures and breathing passages. |
| Nervous tissue | Specialized tissue that transmits electrical signals throughout the body for communication and control. Includes neurons and supporting cells that carry messages between body parts. |
| Organ level | The organizational level where different tissues work together to perform specific functions. |
| Organism level | The complete living individual with all systems working together to maintain life. Represents the integration of all organizational levels. |
| Palmar | The back surface of the front limb from the carpus (wrist) down to the paw. |
| Pastern | The region of a horse's leg between the fetlock joint and the hoof. |
| Peritoneum | The smooth membrane that lines the abdominal cavity and covers abdominal organs, providing protection and reducing friction. |
| Physiology | The study of how body parts function and work together. xxxx examines the processes and mechanisms that keep the body alive and healthy. |
| Plantar | The back surface of the hind limb from the tarsus (hock) down to the paw. |
| Pleura | The smooth membrane that lines the thoracic cavity and covers the lungs, reducing friction during breathing movements. |
| Poll | The top of a horse's head between the ears, where the skull meets neck. |
| Proximal | Closer to the body's center or point of attachment. On limbs, xxxx structures are nearer to where the limb connects to the body. |
| Radiograph | An X-ray image that shows internal body structures using ionizing radiation. These two-dimensional images help identify injuries and diseases. |
| Regional anatomy | The study of body structures organized by specific areas or regions, such as the head, neck, or limbs, rather than by body systems. |
| Right lateral view | A radiographic projection where the animal lies on its right side, with the X-ray beam entering the left side and exiting through the right side. |
| Rostral | Toward the nose, used specifically when describing structures on the head. This term replacing "cranial" when referring to facial features. |
| Sagittal plane | Any plane that runs lengthwise through the body, dividing it into unequal left and right portions. Multiple of these planes exist parallel to the median plane. |
| Spinal cavity | The space within the vertebral column that houses and protects the spinal cord. This cavity is part of the dorsal body cavity system. |
| Stifle | The joint in a horse's hind leg, located in the upper portion of the hind limb near the body. |
| Superficial | Positioned near the body surface, closer to the skin. xxxx structures are external relative to deeper structures. |
| System level | The organizational level where multiple organs work together for major body functions, such as the respiratory or digestive systems. |
| Systemic anatomy | The study of body structures organized by organ systems, such as studying all parts of the digestive system together. |
| Tailhead | The base of the tail where it attaches to the body, located at the top of the hindquarters in horses. |
| Thoracic cavity | The space above the diaphragm that contains the heart, lungs, and major blood vessels, all surrounded by the ribcage for protection. |
| Tissue level | The organizational level where similar cells group together to perform common functions. |
| Transverse Plane | An imaginary plane that runs crosswise through the body, dividing it into cranial (head-end) and caudal (tail-end) sections. |
| Ventral | Toward the belly or underside of the body. In standing animals, xxxx refers to the side opposite the spine. |
| Ventral body cavity | The large body cavity that contains most internal organs, divided by the diaphragm into thoracic and abdominal cavities. |
| Ventrodorsal (VD) view | A radiographic projection where the X-ray beam travels from the belly to the back with the patient lying on its back. |
| Visceral | Relating to the internal organs within body cavities and their protective coverings. xxxx structures are the organs themselves and their associated membranes. |
| Withers | The highest point of a horse's back located at the top of the shoulders between the neck and back where the shoulder blades meet. |
| Abdominal cavity | The space below the diaphragm that contains digestive, urinary, and reproductive organs. This cavity is lined with peritoneum membrane and houses organs like the stomach, intestines, liver, kidneys, and bladder. |
| Anatomy | The study of body structures and their physical relationships. Examines what body parts looks like, where they're located, and how they're arranged relative to each other. |
| Barrel | The midsection or ribcage area of a horse's body. This region encompasses the thoracic cavity and represents the widest part of the horse's torso. |
| Bilateral symmetry | Having left and right sides that mirror each other. Most animals have paired structures like legs, kidneys, and lungs that appear as approximate mirror images. |
| Brisket | The chest area of a horse between the front legs. This region corresponds to the front part of the thoracic cavity and sternum area. |
| Cannon | The lower leg region of a horse between the knee and hock and the fetlock joint. |
| Caudal | Toward the tail end of the body. Any structure positioned closer to the tail is described as xxxx relative to structures closer to the head. |
| Cellular level | The organizational level where individual cells carry out specialized functions. Cells are the basic units of life that maintain their own homeostasis through membrane control. |
| Cephalic vein | A major vein running along the front surface of the front leg, commonly used for blood collection and IV catheter placement. |
| Cranial | Toward the head end of the body. Any structure positioned closer to the head is described as xxxx relative to structures closer to the tail. |
