Unit 6 CHATGPT Flashcards
(21 cards)
What is a tissue?
A group of structurally and functionally related cells and the materials surrounding them.
What is the main benefit of having tissue-level organization?
It allows for division of labor among cells, increasing efficiency in bodily functions.
Describe the structure of epithelial tissue.
Tightly packed cells with minimal extracellular matrix, covering surfaces or forming glands.
Describe the structure of connective tissue.
Sparse cells in an extracellular matrix with protein fibers and ground substance.
Describe the structure of muscle tissue.
Elongated cells (fibers) that contract to produce movement.
Describe the structure of nervous tissue.
Composed of neurons with long processes and supporting glial cells.
What is the function of epithelial tissue?
Protection, absorption, secretion, and sensation.
What is the function of connective tissue?
Binds, supports, and protects other tissues and organs.
What is the function of muscle tissue?
Produces movement and force.
What is the function of nervous tissue?
Transmits electrical impulses and processes information.
What are the five types of connective tissue?
Fluid, loose, dense, cartilage, bone.
How do the three types of muscle tissue differ?
Skeletal: voluntary, moves bones.
Cardiac: involuntary, pumps blood.
Smooth: involuntary, moves substances through organs.
Name and describe the two main nervous tissue cell types.
Neurons: transmit signals.
Neuroglia: support, nourish, and protect neurons.
Structure-function of simple squamous epithelium?
Thin, flat cells allow for rapid diffusion (e.g., lungs).
Structure-function of stratified squamous epithelium?
Multiple layers protect against abrasion (e.g., skin, esophagus).
Structure-function of fluid connective tissue?
Blood has cells suspended in plasma to transport materials.
Structure-function of loose connective tissue?
Loosely arranged fibers allow support and flexibility.
Structure-function of dense connective tissue?
Densely packed collagen fibers provide tensile strength.
Structure-function of cartilage?
Firm but flexible matrix cushions joints and structures.
Structure-function of bone?
Dense, calcified matrix provides rigid support and protection.
Structure-function of nervous tissue?
Neurons transmit impulses; glial cells provide support.
