Anatomy Midterm

What does a physiological study involve

it investigates how living organisms function, typically involves experiments, measurements, and observations at the molecular, cellular, tissue, organ or organism level to understand biological mechanisms.

What are different types of anatomical study?

gross anatomy, microscopic anatomy (histology and cytology), developmental anatomy, comparative anatomy, surface anatomy, pathological anatomy, regional anatomy, systemic anatomy

Knowledge of the structure of body parts helps us understnad the function which one is adequate reprfesentation of that principle

When ionic compounds disolve in water their ions?

dissociate

cations and anions that disscoiate in water are sometimes called

electrolytes

What is an electrolyte

a substance that dissolves in water to produce ions, allowing the solution to conduct electricity, examples include salts, acids, and bases

what makes an atom neutral

an atom is neutral when it has the same number of protons as electrons

Normal ph for blood is 7.35 to 7.45 is the normal range for blood and its critical because enzymes ?

work best in that range

what molecule is produced as a waste product of the metabolism of glucose by cells?

what qualifies something as an organic compound?

carbon dioxide

what is the difference between biomolecules

carbs used for immediate fuel, lipid is stores fuel, lipid is used for transport, protection, control, and nucleic acid is dna and stuff

glucose is major nutrients for most body cells

it is broken down during cellular respiration to produce atp the molecule that powers cellular activities

glycogen is the stored form of carb for

animal

Rna vs Dna what are sugars found in both

ribose and dioxyribose

what is starch

starch is a type of carbs made up of many glucose molecules linked together. it is a way plants store energy

what is cellulose

not digestiable to humans but it is a type of carb found in the cell walls of plants and it provides structure and support to the plant

the plasma membrane is descibed as being selectively permeable

it means it controls what enters and leaves the cell

vitamin a a fat soluble vitim moves across plasma membrane into the cell by

dissolving into lipid bilayer

four primary tissue types

epithelial, connective, muscle, nervous

what is the mesoderm when it comes to the embryonic layer

is one of the three primary embryonic layers that form during early develoment, it is the middle layer, located between the ectoderm and endoderm. It gives rise to strucutres like muscles, bones, the heart, blood vessels, and kidneys

the extracellular material found in connective tissue is called what?

extracellular matrix

What is a biopsy

youll know it when u see it on the test lmao

Write down ecto, meso, and endoderm and what the difference between each?

ectoderm is outer layer and forms skin hair and nails and the nervous system, mesoderm devlopes muscles, bones, and blood vessels and internal organ, endoderm gives ruse to the lining of the digestive tract,respiratory system, liver, pancreas, and bladder

what seperates epithelial tissue from all the other tissue types

prescense of basement membrane

which of the following is function of epithelial tissues

secretion and absorption of molecules

how do we classify different types of epithelial

shape of the cells and number of types of cell barriers

stratified epithelium

multiple layers

keratinized v non keratinized. where would u see it

karanized(found on outer layer of skin) is a tough protective protein called keratin, non keratinized(mouth, vagina, esophagus)th does not have a lyer or keratin and it is softer and more flexible, and moist

describe epidermis of skin

the epidermis is the outermost layer of skin. its made up of several layers of cells with top layer being made of dead cells filled with kertain. the epidermis is a barrier from harmful things

of organelles in cells which one is most important in secretory epiuthellial cells

golgi

what happens to squamous epithelial if you stretch it too far

could tear, lose their structural integrity, or become misaligned.
