Introduction To Anatomy & Physiology Flashcards
(100 cards)
What is physiology?
Physiology is the study of how the body functions.
What is anatomy?
Anatomy is the study of the structure of the animal body and the relationship among its parts.
Define microscopic anatomy.
The study of cells and tissues that require a microscope to visualize.
Define macroscopic anatomy.
The study of structures that can be seen without a microscope and is also referred to as gross anatomy.
The _____ plane divides the animal down the center into equal left and right halves. Also known as a midsagittal plane.
Median
The _____ plane runs the length of the body and divides the body parallel to the median plane into left and right parts that are not necessarily equal.
Sagittal
**A body can have multiple sagittal planes on the right and left sides.
Dorsal plane
Perpendicular to the median plane. Divides the body into two parts, one containing the belly, the other containing the back.
Transverse plane
Lies perpendicular (at a right angle) to both the median plane and the dorsal plane. Divides the body into two sections - one containing the head and the other the tail.
Cranial
Toward the head
Caudal
Toward the tail end
Rostral
Refers to parts of the head that are closer to the tip of the nose.
Dorsal
Closer to the back or spine.
Ventral
The opposite of dorsal; nearer to the side of the animal that is closest to the ground. Toward the belly.
Lateral
A position farther away from the median plane (toward the side - either left or right).
Medial
A position closer to the median plane (which goes through the spine/center of the body).
Anterior
In front of or in the forward part of an organ (i.e. The side you see when you stand face to face with an animal.)
Posterior
The opposite of anterior; it refers to a position or surface toward the rear of the animal.
Proximal
Refers to a body part’s being closer to the main portion of the body. Closer to the origin of flow.
Distal
Describes a body part that’s placed farther out from the main portion of the body. Closer to the destination of flow.
Superficial
Refers to a position that’s located toward the surface of a structure.
Deep
Refers to a position located toward the center of a structure.
Orad
Refers to movement within the gastrointestinal system in the direction of the mouth. ➡️
Aborad
Motion in the direction away from the mouth.
Bilateral symmetry
The organism’s left and right halves are approximate mirror images of each other.
