Structure & Function
This is the study of the structure of body parts and their relationship to one another
Anatomy
This is the maintenance of relatively stable internal conditions despite continuous changes in environment.
Homeostasis
Name three functions of epithelium.
Protection, absorption, filtration, excretion, secretion, and sensory reception
All connective tissues have three main elements.
Ground substance, fibers, and cells
Muscle cells possess myofilaments made up of _____ and ____ proteins that bring about contraction.
actin, myosin
What type of membrane lines closed ventral body cavities? List three examples.
Serous membranes line closed ventral body cavities. Three examples are pericardium, pleurae, and peritoneum.
The principle of complementarity of structure and function states this.
Function always reflects structure. What a structure can do depends on its specific form.
When the body responds to a stimulus by enhancing or exaggerating the original stimulus.
Positive feedback
Name the tissue: cells are flattened laterally, and cytoplasm is sparse. Functions where rapid diffusion is priority.
Simple squamous
I am: Most widely distributed CT, Supports and binds other tissues, Universal packing material between other tissues, Contain fibroblasts that secrete loose arrangement of mostly collagen fibers
Loose Areolar CT
I: Attached to and causes movement of bones; Contain multiple nuclei.
Skeletal muscle
Name the correct order of the structural organization of the body.
atoms, molecules, organelles, cells, tissues, organs, organ system, organism
___: Body erect, feet slightly apart, palms facing forward with thumbs pointing away from body
Standard anatomical position
Name the tissue: cells vary in height and appear to be multi-layered and stratified, but the tissue is in fact single-layered simple epithelium.
Pseudostratified columnar epithelium
I have: Very high tensile strength; can withstand high tension and stretching; Closely packed bundles of thick collagen fibers run parallel to direction of pull (Fibers appear as white structures), Fibers slightly wavy, so stretch a little
Dense regular CT
I: Found mainly in walls of hollow organs (other than heart); Involuntary control; Have no visible striations
Smooth muscle
This organ system protects and supports body organs; provides a framework the muscles use to cause movement. Blood cells are formed within and stores minerals.
Skeletal system
This divides the body vertically into anterior and posterior parts.
Name the tissue: two or more layers of cells, new cells regenerate from below, durable because protection is the major role.
Stratified squamous
I am: Most abundant cartilage type; “gristle”; Appears as shiny bluish glass; Found at tips of long bones, nose, trachea, larynx, and cartilage of the ribs
Hyaline cartilage
I: Found only in walls of heart, contains striations; but cells have only one nucleus.
Cardiac muscle
This organ system picks up fluid leaked from blood vessels and returns it to blood. Disposes of debris. Houses white blood cells involved in immunity.
Lymphatic system
Part of the thoracic cavity, this contains the pericardial cavity as well as surrounds other thoracic organs, such as esophagus, trachea, etc.
Mediastinum
Name the tissue: Forms lining of hollow urinary organs, basal layer cells are cuboidal or columnar, ability of cells to change shape when stretched
Transitional epithelium
I: Support and protect body structures; Stores fat and synthesizes blood cells in cavities; Have more collagen compared to cartilage; Have inorganic calcium salts
Bone (osseus) tissue
These cells support, insulate, and protect neurons
Glial cells
