WEEK 1: Terminology Flashcards
Differentiate between anatomy and physiology
Anatomy = is the study of the structure of the body
i.e., a blood vessel is circular, surrounded by layer of endothelial cells with small caps between them.
Physiology = the study of how body structures function
i.e., the gaps between the endothelial cells permits the fusion of small ions and molecules in/out of the blood vessel.
What are planes?
Planes are 2D slices through a 3D space.
They are used to divide the body.
3 PLANES = sagittal, frontal (coronal) and transverse.
What is the sagittal plane?
A vertical line that divides the body into left and right sections.
Produces forward and backwards movements (flexion/ extension).
What is the frontal plane?
A vertical line that divides the body into anterior and posterior sections.
Produces sideways movements (abduction/ adduction).
What is the transverse plane?
A horizontal line that divides the body into upper (superior) and lower (inferior) sections.
Produces rotational movements (can be opposite or same side rotation).
Anterior
Pertaining to the front of the body i.e., the kneecap is on front of the leg.
Posterior
Pertaining to the back of the body. I.e., shoulder blades sit on the posterior.
Superior
Higher than another point of reference i.e., the head is superior to the feet.
Inferior
Lower than another point of reference i.e., the feet are inferior to head.
Proximal
Relatively near a point of origin or attachment i.e., the shoulder is closer to the trunk and so it is proximal to the hand.
Distal
Relatively distant from a point of origin or attachment i.e., the hand is distal to the shoulder.
Medial
Toward the middle of the body i.e., the nose medial to the ears.
Lateral
Away from the middle of the body i.e., the ears are lateral to the nose.
Superifical
Relatively close to the body surface i.e., the skin is superficial, or the ribs are superficial to the lungs.
Deep
Relatively far from the body surface i.e., deep stab wound.
Prone
Describing a reclining body, face down i.e., your face is face down in a plank position.
