Need to know from the packet

Feedback Loop: 1

Stimulus produces change in variable

Feedback Loop: 2

Receptor detects change

Feedback Loop: 3

Input: Information sent along from afferent pathway to control center

Feed Back Loop: 4

Output: Information sent along efferent pathway to effector

Feedback Loop: 5

Response of effector feeds back to reduce the effect of stimulus and returns variable to homeostatic level

Feedback Loop:

Afferent pathway=to the left of the control center

Feedback Loop:

Efferent Pathway= to the right of the control center

What is the relationship between anatomy and physiology

How its put together dictates how well it works

Tissue: Four Main Types

epithelial, connective, muscle, and nervous tissue

Tissue: Structure of epithelial tissue

A sheet of cells that covers body surfaces or cavities

Tissue: Function of epithelial tissue

Protection (multiple layers) , Absorption (Simple Layer), filtration, excretion, secretion, and sensory reception

Tissue: Classification of epithelial tissue

All epithelial tissues have two names: Simple epithelia- single layer
Stratified epithelia- layered

Tissue: Characteristics of connective tissue

Have varying degrees of vascularity (cartilage is avascular, bone is highly vascularized)

Tissue: Components of connective tissue

Ground substance, fibers, and cells

Tissue: Types of connective tissues

Connective tissue proper, cartilage, bone, and blood

Tissue: Cells found in connective tissue

"Blast" cells- an immature form of a cell that actively secretes ground substance and ECM fibers
"Cyte" cells- Mature, less active form of "blast" cell that now becomes part of and helps maintain health of matrix

Bone

Supports and protects the blood cells in cavities

Blood

Consists of cells surrounded by matrix (plasma)
