Cards

Term
Anatomy
Definition
Deals with the form and structure of the body and its parts
Term
Physiology
Definition
Deals with the functions of the body and its parts
Term
Microscopic anatomy
Definition
Deals with structures so small we need a microscope to see them clearly, ie. cells and tissues
Term
Macroscopic anatomy
Definition
a.k.a. Gross anatomy

Deals with body parts large enough to be seen with the unaided eye, ie. organs, muscles, and bones.
Term
Regional anatomy
Definition
All components of each region of the body are examined, ie. anatomy of the neck would include all cells, tissues, blood vessels, nerves, muscles organs, and bones.
Term
Systemic anatomy
Definition
Deals with the systems of the body, ie. nervous system and skeletal system.
Term
The four anatomical planes of reference:
Definition
Sagittal plane
Median plane
Transverse plane
Dorsal plane
Term
Sagittal plane
Definition
A plane that runs the length of the body and divides it into left and right parts that are not necessarily equal halves.
Term
Median plane
Definition
a.k.a. Midsagittal plane

A special kind of sagittal plane that runs down the center of the body lengthwise and divides it into equal left and right halves.
Term
Transverse plane
Definition
A plane across the body that divides it into cranial and caudal parts that are not necessarily equal.
Term
Dorsal plane
Definition
It divides the body into dorsal and ventral parts that are not necessarily equal.
Term
Left and right will always refer to whose perspective in anatomy?
Definition
The animal's.
Term
Cranial
Definition
Towards the head.
Term
Caudal
Definition
Towards the tail.
Term
Xiphoid Process
Definition
Caudal end of the sternum.
Term
Rostral
Definition
Towards the tip of the nose.
Term
Dorsal
Definition
Towards the back.
Term
Ventral
Definition
Towards the belly.
Term
Medial
Definition
Towards the median plane.
Term
Lateral
Definition
Away from the median plane.
Term
Deep
Definition
Towards the center of the body.
Term
Superficial
Definition
Towards the surface of the body.
Term
Proximal
Definition
Towards the body. Used to describe extremities.
Term
Distal
Definition
Away from the body. Used to describe extremities.
Term
Carpus
Definition
The proximal distal dividing line for the front leg.
Term
Tarsus
Definition
The proximal distal dividing line for the rear leg.
Term
Palmar
Definition
The back surface of the of the front leg distal to the carpus.
Term
Plantar
Definition
The back of the hind leg distal to the tarsus.
Term
Bilateral symmetry
Definition
The left and right halves of an animal's body are essentially mirror images.
Term
Dorsal Body Cavity
Definition
Contains the brain and spinal cord and consists of the cranial cavity and spinal cavity.
Term
Ventral Body Cavity
Definition
Contains most of the soft organs, viscera, of the body. Divided by the diaphragm into the thoracic cavity and the abdominal cavity.
Term
Pleura
Definition
Covers the organs in the thoracic cavity.
Term
Visceral Layer
Definition
The layer that lies on the viscera.
Term
Parietal layer
Definition
The layer that lines the cavity.
Term
Peritoneum
Definition
The membrane that lines the abdominal cavity.
Term
Cells
Definition
The basic functional units of animal life; the smallest subdivisions of the body that are capable of life.
Term
Tissues
Definition
Specialized cells grouped together.
Term
Epithelial tissue
Definition
Composed entirely of cells, its main job is to cover body surfaces. Also forms glands that secrete useful substances and excrete wastes.
Term
Connective tissue
Definition
Holds the body together and gives it support. Range from very soft, such as adipose tissue (fat) to very firm such as cartilage and bone.
Term
Muscle tissue
Definition
Moves the body inside and out. Consists of three types: skeletal, cardiac and smooth.
Term
Skeletal muscle
Definition
Moves the bones if the skeleton and is under conscious nervous system control.
Term
Cardiac muscle
Definition
Makes up the heart and works automatically without conscious effort.
Term
Smooth muscle
Definition
Found in internal organs such as the digestive tract and urinary bladder.
Term
Nervous tissue
Definition
Transmits information around the body and controls body functions.
Term
Organs
Definition
Made up of groups of tissues that work together for common purposes.
Term
Systems
Definition
The most complex level of body organization. Groups of organs involved in a common set of activities.
Term
Homeostasis
Definition
The maintenance of a dynamic equilibrium in the body.
