3 parts of the Cell Plasma, Cytoplasm, Nucleus plasma membrane controls movement of substances into or out of the cell Cilia short hair- like projections for movement of substances along cell surface Cytosol Intercellular fluid Mitochondria site of energy production by cellular respiration Ribosomes site for protein synthesis Smooth Endoplasmic Reticulum -SER Site of steroid and fatty acid synthesis Lysomomes small vesicles with digestive ...

cells are the basic, living, structural, and functional units of the body plasma membrane 1. Acts as a barrier separating inside and outside of the cell. 2. Controls the flow of substances into and out of the cell. 3. Helps identify the cell to other cells (e.g., immune cells). 4. Participates in intercellular signaling. cytoplasm consists of all the cellular contents between the plasma membrane and the nucleus. This compartment has two components: cytosol and organelle...

Tight junctions can be found in the urinary bladder. True False True Adherens junctions are composed of a protein plaque, microfilaments and transmembrane proteins. True False True Like the adherens junctions, desmosomes rely on microfilaments for stability. True False False Hemidesomsomes add resistance to frictional forces. True False True Connexons allow ions and electric impulses to travel from one cell to another. True False True G...

A molecule ...

Components of the homeostatic control loop receptor, control center, effector Negative feedback -works to oppose change -brings condition back to a set point Positive feedback -works to enhance change -brings condition further away from a set point Tonicity relates to how the solution influences the shape of body cells Hypotonic solution RBC undergoes hemolysis (swelling) Hypertonic solution RBC undergoes crenation (shrinking) Osmosis -concentra...

What 4 ways do you examine the body? Inspection, Palpation, Auscultation and Percussion Inspection Seeing the body Palpation to examine by touch Auscultation Listening with a stethoscope Percussion taking hands and beating over certain parts of body Medical Imaging methods of viewing the inside of the body without surgery, i.e. radiology Gross Anatomy Study of structures that can be seen with the naked eye Histology the study of the micros...

The study of human structure Anatomy The study of human function Physiology A tendency for organisms to maintain a balanced or constant internal state Homeostasis A state of balance Equilibrium Consequences of homeostatic imbalance Illness or death Thermoregulation Process A feedback loop in which a system responds to a change by reversing that change, or by decreasing the rate at which the change is occurring. (Ex. thermoregulation) Negative Feedb...
