Module 1 & 2 | Anatomy & Physiology Flashcards
The largest molecules in the Body and include 2 major classes
Nucleic Acids
Measures the relative concentration of hydrogen ions in various body fluids
pH Level
Term when it is near to the middle of your body
Medial
Term used when it’s going back to your body
Proximal
Scan of half of your front and back
Coronal plane
A body position facing the floor
Prone
A body position laying on the floor and facing upwards
Supine
Smallest unit of life
Cell
The ability of a solution to change shape of cells by altering the cells
Tonicity
What solution is it when cells retain their normal size and shape
Isotonic solution
Requires transport proteins that combine specifically and reversibly with the transported substance
Active Transport
Cell surface proteins that mediate the interaction between cells, or between cells and the extracellular matrix (ECM).
Cell Adhesion Molecules (CAMs)
process in which a ligand (chemical messenger) binds a specific receptor and initiates a response
Chemical signaling
cells come together, touch and recognize one another. Useful in development and immunity
Contact Signaling
Powerplants of the cell
Mitochondria
Digests all kids of biological molecules including bacteria and cell debris
Lysosomes
System of organelles that work together mainly to Produce, degrade, store and export biological molecules, Degrade potentially harmful substances
Endomembrane System
whiplike, Its actions move substances in one direction across the cell surfaces
Cilia
Control center and contains the instructions to build nearly all the body’s proteins
Nucleus
Series of changes a cell goes through from the time it is formed until it reproduces
Cell Cycle
A subphase when DNA is replicated
S subphase
division of the cytoplasm
Cytokinesis
Groups of cells that are similar in structure and perform a common or related function
Tissues
Sheet of cells that covers a body surface or lines a body cavity, a boundary-forming tissue
Epithelial Tissue
Does much more than just connect body parts
Connective Tissue
Well-vascularized tissues that are responsible for most type of body movement
Muscle Tissue
This is the Main component of the nervous system (brain, spinal cord and nerves) which regulates and controls body functions
Nervous Tissue
A anatomical term of the ears
Auricular
Study of Chemical composition and reactons of living matter
Biochemistry
Contains carbon and made by living things
Organic Compound
Includes sugar and starches
Carbohydrates
Componds that lack carbon except carbon dioxide and carbon monoxide
Inorganic Compound
Building blocks of protein
Amino acids
Anatomical term for Fingers
Digits
Anatomical term for eyes
Orbital region
Anatomical term for the chin
Mental Region
Before a cell can divide, its DNA must be _______
Replicated Exactly
programmed cell death, rids the body of cells that are programmed to have a limited life span.
Apoptosis
How many are the basic tissues types.
Four
Type of protein that protect against diseases
Defensive Proteins
Type of protein that functions as the mechanical support
Structural Proteins
