Basic Anatomy Flashcards
Manufacture proteins
Ribosomes
Necessary for cell division
Centrioles
Manufactures lipids, responsible for maintaining cell walls.
Smooth endoplasmic reticulum
Manufactures proteins with ribosomes attached to its surface. Proteins are for export
Rough endoplasmic reticulum
Not attached to rough endoplasmic reticulum, these manufacture protein for the cell itself.
Free ribosomes
“Quality control” for produced proteins
Golgi apparatus
Contains enzymes that break down part of a cell.
Lysosomes
Basic fuel of the body
ATP - Adenosine TriPhosphate
What produces ATP?
Mitochondria
What cells form bones?
Osteoblasts
Tissue covering body surfaces, internal organs, and make up the glands.
Epithelial tissue
Tissues filling the internal spaces of the body, bind, support, and protect body structures.
Connective tissues
Tissues including skeletal muscles, heart, and muscular walls of hollow organs.
Muscle tissues
Tissues carrying information from one part of the body to another.
Nervous tissues.
What is the axial skeleton?
Skull, face, thoracic cage, and vertebral column
What is the appendicular skeleton?
The arms, legs, their connection points, and the pelvis.
What is the hilum?
The point of entry into the lungs.
What is the typical resting tidal volume?
500 mL
What is tidal volume?
Amount of air moved in one breath.
What does a chronotropic effect do?
Effects rate of heart contraction
What does a dromotropic effect do?
Effects rate of electrical conduction
What does an inotropic effect do?
Effects strength of contraction
What response does alpha1 stimulation produce?
Vasoconstriction and increase in sweat gland activity
What response does alpha2 stimulation produce?
Blocks norepinephrine release
What response does beta1 stimulation produce?
In the heart, increase in rate, force, and electrical activity.
In vessels, vasodilation.
What response does beta2 stimulation produce?
Bronchodilation and glycogenolysis
What response does beta3 stimulation produce?
Glycogenolysis
What are the four catecholemines?
Epinephrine, norepinephrine, dopamine, and serotonin
What is the innermost layer of a vessel?
Tunica intima
What is the middle layer of the vessel? What does it do?
Tunica media
It is made of smooth muscle cells for expansion and contraction of the vessel.
What is the outermost layer of the vessel?
Tunica adventitia
What is stenosis?
Narrowing of a lumen of an artery for any reason.
How much blood do most people have?
5L
