What is the relationship between anatomy and physiology
What is the function of mast cells
secrete heparin and histamine
Define ground substance
unstructured material that fills the space between cells
Which body cavity is larger? Dorsal or ventral
ventral
What is the composition of bone
70% minerals and 30% protein (collagen) 99% Ca, 85% P, 60% Mg
Define matrix
Innermost compartment of the mitochondrion
Where are mucous membranes located?
Lines inside of organs that are open to the exterior
What is simple epithelial tissue
Thin and all cells have the same polarity, so the distance from thenucleus to the basement membrane does not change from one cell to the next
Where is dense fibrous connective tissue found
-tendons and ligaments; needs to be very strong
What is a tissue?
A tissue is a group of similar cells that work together to carry out a particular function
What is an acid-base reaction?
An acid base reaction is when an acid and a base are placed together and they react to neutralize the acid and base properties.
What is the function of macrophage cells
Carryout phagocytosis.
Distinguish between Collagen and elastin
Collagen are thick threads of the protein collagen. Elastin are composed of a springlike protein.
The two major body cavities
Dorsal Cavity and the ventral cavity.
What is homeostasis and how is it maintained
Homeostasis- conditions inside an organism do not change maintained through negative feedback
What are goblet cells and where are they found?
Mucous producing cells. They are found in the epithelium of the GI tract and the respiratory tract except in the alveoli
What are the reactants and products of a reaction
Reactants are substances that participate in a reaction, while products are substances that form as a result of a reaction
What is an endocrine gland?
Releases secretion into internal fluids (no ducts used)
What is the function of fibroblast cells
Responsible for synthesis of fibers and intercellular ground substance (wound repair)
What is an exocrine gland and give an example?
Secrete their products on to the surfaces of organs Ex) Sweat glands
What is negative feedback?
a system to keep body conditions within a set normal range by reversing any upward or downward shift
What is matter?
anything that occupies space and has mass
What are neurons?
basic building blocks of the nervous system
What makes up bones
bone tissue, marrow, cartilage, periosteum
What is the ph range for a base
greater than 7
What makes up the axial portion of the body
head, neck, trunk
What is the ph range of acid
less than 7
What is the structure of protein
made of amino acids (20 different ones), held together by peptide bonds making polypeptide chains
What is stratified epithelial tissue
multiple layers of cells
What are the components of an atom
protons, neutrons, electrons
Where is fibrous connective tissue found?
tendons and ligaments
What is phagocytosis?
the ingestion of bacteria or other material by phagocytes and amoeboid protozoans.
What are neuroglial cells?
they are support cells that surround neurons and provide nutrients, immune support, and appropriate external environment
