Term
What is the difference between gross and microscopic anatomy?
Definition
Gross anatomy: Large visible structures. Visible to the naked eye.
Microscopic: Examines cells and molecules. Not visible to the naked eye.
Term
From simplest to complex, what are the levels of organization?
Definition
Cellular, tissue, organs, organ systems, organism.
Term
Define Homeostasis
Definition
Maintaining a stable internal environment.
Term
What is a cell membrane and it's functions?
Definition
The outermost part of the cell. It protects and regulates.
Term
List 2 basic components of the cell membrane
Definition
The phospholipid bilayer and transporter proteins.
Term
How does water cross the cell membrane?
Definition
It goes through diffusion of a channel.
Term
How does oxygen cross the cell membrane?
Definition
It goes through simple diffusion similar to water.
Term
What is a ribosome? What does it do?
Definition
An organelle that synthesizes proteins
Term
What is Rough ER?
Definition
Its ribosomes manufacture all proteins and it is a membrane factory.
Term
What is Smooth ER?
Definition
It catalyes: lipid metabolism, cholesterol synthesis, and synthesis of lipoproteins. absorption, transportation, detoxification, and breakdown.
Term
Cilia
Definition
Moves substances across the cell surface.
Term
Microvilli
Definition
Shaggy hairs that increase the surface area of the cell membrane.
Term
Golgi Apparatus
Definition
Repackaging. Secretes to the outside of the cell.
Term
Centrioles
Definition
Divide the cells and help with cell production.
Term
Cytoskeleton
Definition
Structural protein for strength and shape. Ziplines for organelle and molecule transport.
Term
Mitochondria
Definition
Provide energy.
Term
Nucleus
Definition
Control center. Contains code for DNA.
Term
What molecules do your DNA code for?
Definition
Proteins
Term
Other than the nucleus, what organelles are used in protein formation?
Definition
Rough ER
Term
Why are some proteins made in the rough ER and some made by free ribosomes in the cell?
Definition
Because some are stored and some are secreted
Term
How does the nucleus determine cell function?
Definition
It contains code for protein structure which allows it to determine the function for the cell.
Term
What is a tissue?
Definition
A collection of cells that perform specific functions.
Term
What does muscle tissue do?
Definition
Allows contraction and movement.
Term
What is neural tissue specialized to do?
Definition
Carry electric signals
Term
What are the four tissue types?
Definition
Connective, neural, epithelial, and muscle.
Term
Five characteristics that epithelia share
Definition
1) Cellularity 2)Polarity 3)Attachment 4) Avascularity 5)Regeneration
Term
Functions of epithelial tissue
Definition
Protection and permeability
Term
Where are epithelia found?
Definition
They cover the body surfaces and line cavities.
Term
Why do epithelium have columnar cells and not squamous cells?
Definition
For protection.
Term
f. Based on the thickness of the epithelium (number of cells stacked up), what would you suppose is the function of a stratified epithelium? What would you suppose the function of a simple epithelium would be?
Definition
Protection. Simple: Absorption, secretion, and filtration.
Term
Where might you find a stratified squamous epithelium or simple squamous epithelium?
Definition
Stratified: Skin surface and lining of the mouth. Simple: In the kidneys.
Term
How does connective tissue contribute to the framework of the body – where are connective tissues (CT) found?
Definition
It supports, fills, transports, stores, and isolates. Connective tissues are found in cartilage, bone, and blood.
Term
What are the extracellular fiber types of connective tissue? How would changing a connective tissue’s fiber type change its function?
Definition
Reticular, collaged, and elastic fibers. It would change its location and function.
Term
What are: loose CT, dense CT, liquid CT, bone & cartilage?
Definition
Loose CT: Areolar, adipose, reticular.
Dense CT: Dense regular, dense irregular, and elastic.
Liquid CT: Blood.
Bone: Calcified for weight and support.
Cartilage: flexible, resilient rigidity. Has qualities intermediate between dense connective tissue and bone. Shock absorption and protection.
Term
Compare and contrast dense regular CT and dense irregular CT.
Definition
Dense regular CT: Is tightly packed and parallel to collagen fibers. (Tendons and ligaments)
Dense irregular CT: Strength in many directions. Interwoven networks of collagen fibers.
Term
What are the functions of dense and irregular connective tissue?
Definition
Regular: attachment and stabilization. Irregular: Strength.
Term
Where are regular and irregular connective tissue found?
Definition
Regular: Tendons and ligaments. Irregular: skin, cartilage, bones, and ligaments.
Term
Where does the axial skeleton join the appendicular skeleton?
Definition
At the shoulders.
Term
Can you identify the bones of the appendicular skeleton on an articulated figure?
Definition
Shoulder, arm, hand, and pelvic girdle.
Term
Which bones make up the limbs?
Definition
Humerus, ulna, radius, phalanges, femur, patella, tibia, fibula, phalanges.
Term
Which bones make up the pectoral and pelvic girdles?
Definition
Pectoral: Clavicle and scapula. Pelvic: ilium, ischium, and pubis. Functions- Pectoral: Connects the upper limbs. Pelvic: Hold in the legs and join the spine. Meet with the sacrum merges with the ilium.
Term
What bone makes the point of your shoulder?
Definition
Achrominion meets the clavicle.
Term
Which bones of the forearm & leg are medial? Which are lateral?
Definition
Forearm: Ulna (Medial), Radius (Lateral). Leg: Tibia (Medial), Femur (Lateral).
Term
What bone makes the point of your lateral wrist?
Definition
Radial
Term
What bones make the medial and lateral bulges of the ankle?
Definition
Talus and calcaneus
Term
Which bones come together to create the pelvis?
Definition
Ischium, ilium, and pubis.
Term
Which bone do you sit upon?
Definition
Coccyx and iliachum
Term
What is between the ulna & radius or the tibia & fibula?
Definition
Ulna and radius-a fibrous sheet.
Term
What is a joint?
Definition
Where two bones connect
Term
What are the three functional classes of joints?
Definition
Synarthrosis, ampiarthrosis, diarthrosis.
Term
Movement: synarthrosis
Definition
No movement
Term
Movement: Ampiarthrosis
Definition
Little movement
Term
Movement: Diarthrosis
Definition
Free movement
Term
What are the three structural categories of joints?
Definition
Fibrous, cartiliganous, synovial
Term
For each structural type, how do the bones come together (what type of tissue is between the 2 bones involved in the joint?)?
Definition
Fibrous: suture, syndesmosis, gomphosis. Cartilaginous: symphisis, synchondrosis. Synovial: saddle, hinge, ball and socket, planar, condyloid, and pivot.
