CH.2 Human Body In Health And Disease (w/ Ventral Cavity) Flashcards
What are atomic reference systems?
Atomic reference systems are used to describe the locations of the structural units of the body.
Ex: right hand is on the right and left hand is on the left
Anatomy is the..
Study of the structures of the body
Physiology is the..
study of the functions of the structures of the body (physi means nature or physical, and -ology means study of).
What is an anatomic position?
Body standing is standard position:
Standing up straight so that body is erect and facing forward.
Holding the arms at the sides with the hands turned so that the palms face toward he front.
What are body planes?
Body planes are imaginary vertical and horizontal lines used to divide the body into sections for descriptive purposes.
The midsagittal plane divides the body into…
Equal left & right halves.
The transverse plane divides the body into…
Superior ↑(upper) and inferior ↓ (lower) portions.
The frontal plane divides the body into …
Anterior or ventral (front) & posterior or dorsal (back) portions.
What is a vertical plane?
An up-and-down plane that is at a right angle to the horizon.
What is a sagittal plane?
A vertical plane divides the body into unequal left and right portions
What is a midsagittal plane?
Also known as the midline, is the sagittal plane that divides the body into equal left and right halves.
What is a frontal plane?
A vertical plane that divides the body into anterior (front) and posterior (back) portions. Also known as the coronal plane, located at right angles to the sagittal plane.
What is a horizontal plane?
A flat, crosswise plane, such as the horizon.
What is a transverse plane?
A horizontal plane that divides the body into superior (upper) & inferior (lower) portions. A transverse plane can be at the waist or at any other level across the body.
Ventral refers to..
The front, or belly side, of the organ or body (ventral means belly side of the body, and -al means pertaining to). Ventral is opposite of dorsal.
