Homeostasis
Explain the difference between anatomy and physiology.
Anatomy=Structures
Physiology= Function and Processes
Describe and give examples of the 4 types of tissue
Epithelial, Connective, Nervous and Muscular tissue
Describe a ligament.
Ligament- a short band of tough, flexible fibrous connective tissue which connects two bones or cartilages or holds together a joint.
What is the normal pH of a healthy person?
7.4
What are the 2 purposes of fontanels?
During birth, fontanelles enable the bony plates of the skull to flex, allowing the child's head to pass through the birth canal. The ossification of the bones of the skull causes the anterior fontanelle to close over by 9 to 18 months.
what is Hemolysis
what is Crenation
H) the rupture or destruction of red blood cells.
C) red blood cells undergo shrinkage and acquire a notched or scalloped surface.
ABCDE rule
: Asymmetry (one half of the mole doesn't match the other), Border irregularity, Color that is not uniform, Diameter greater than 6 mm (about the size of a pencil eraser), and Evolving size, shape or color.
What is the common name for epiphyseal plate?
The growth plate,
What is acidosis? What are the symptoms?
Acidosis is when the pH of the body is very acidic. Symptoms include high respiration and pulse rates, headache, confusion, nausea, weakness, tiredness, lack of appetite
What is the difference between an adult an infant skull?
One of the basic and main differences is that babies have spaces ( the soft spot that pulses from blood flow is the result ) called fontanelles. These spaces exist to help babies be born physically. They close through different stages of life, which interestingly helps medical examiners approximate the age of a skull.
Define osmosis and tonicity.
Osmosis=movement of water through a semipermeable membrane of cells
Tonicity= the concentration of a solution compared to another solution
What is a fibroblast
Fibroblast - a cell in connective tissue which produces collagen and other fibers.
What are the differences between and male and female skeletons?
In males, the jaw bone is generally larger and more pronounced, and the brow is taller. Male skeletons also generally have longer, thicker bones in the arms, legs and fingers. ... This major difference between men and women is the cause of the biggest hallmark feature of a female vs. male skeleton, the pelvis.
When the body’s pH is off, what does it do to return the pH to normal?
The body pulls minerals for bones and blood to reduce the acidity of the blood.
What is the location and function of the periosteum and endosteum?
The periosteum is a membrane that covers the outer surface of all bones, except at the joints of long bones (It serves as protection as well as a channel for the blood supply and nutrients for bone tissue. ). Endosteum is a thin, soft, connective tissue, lining the cavity of long bones like Humerus and Femur. It acts as a coating for the inner compact bone and the trabeculae of the spongy tissue.
Define and give 3 examples of homeostasis in the human body.
body temperature: goosebumps, shivers, sweating,
Oxygen: respiration rate
Sugar: insulin/glycogen cycle
pH: saliva and digestive juices
Delivery of nutrients and oxygen: blood pressure and pulse
what is a skin biopsy?
skin biospy - a doctor cuts and removes a small sample of skin to have it tested.
What is a greenstick fracture?
A greenstick fracture is a fracture in a young, soft bone in which the bone bends and breaks.
Is alkaline or acid blood pH more harmful? Why?
Acidic ; acidic pH removes negative charge of RBC causing them to clump together (clots) reducing the oxygen delivery to tissues.
What is osteomyelitis?
Osteomyelitis is an infection in a bone.
Explain the difference between communicable disease and contagious disease.
Communicable disease is a disease that can spread in a variety of ways,
Contagious disease is a type of communicable disease in which the disease spreads person-to person.
Describe the function of the eponychium and nail matrix.
Eponychium - protect the area between the nail and epidermis from exposure to bacteria.
Nail Matrix -creates new skin cells, which pushes out the old, dead skin cells to make your nails.
What is Kyphosis?
Kyphosis is a spinal disorder in which an excessive outward curve of the spine results in an abnormal rounding of the upper back.
Explain why you cannot give a patient 0% saline (straight water) in an IV.
Using pure distilled water (hypotonic) would cause water to rush into the cells to dilute the contents and reach equilibrium, resulting in popped cells.
What is the difference between osteocytes, osteoblasts and osteoclasts?
The principal difference between osteoblasts and Osteocytes is their relative location in bone. ... Osteoclasts are derived from pluripotent cells of bone marrow and lie in the region of bone resorption in pits called Howship's lacunae. Osteoclasts primarily responsible for bone resorption and help for bone remodeling.
