Term
Animal tissues are held together by the ___ and ____.
Definition
extracellular matrix and cell junctions
Term
4 major categories of tissue are
Definition
epithelial, connective, muscle and nervous
Term
epithelial ( some specialized for absorption or secretion like mucous)
Definition
Tightly packed cells that are protective layers, cover the body and line organs and body cavities. 1 free surface is exposed to air or fluid, and the other surface attached to ECM ( basement membrane).
Term
Body parts and corresponding epithelial tissue-
Definition
Lung- simple squamous
kidney- simple cuboidal
intestine- simple columnar
esophagus- stratified squamous
skin- stratified squamous
Term
gladular epithelium
Definition
exocrine ( secrete product onto surface via ducts
endocrine- secrete products into a tissue, no ducts needed.
Term
Connective tissue
Definition
basic support of body, providing attachment sites and protecting organs. characterized by a sparse cell population
Term
Loose connective tissues
Definition
most common type. cells are fibroblasts. form is loose, collagenous fibers. it functions as a flexible framework around organs.
Term
Fibrous connective tissues, is ligaments.
Definition
cells are fibroblasts. form is dense masses of collagen. irregular fibers are impact resistant.
Term
Andipose tissue
Definition
form is a specialized loose connective tissue
Term
Cartilage
Definition
form is collagenous, strong and flexible. form skeleton, resists compression.
Term
Bone
Definition
hard strong, form is mineralized hardened matrix of collagen and Ca. there are compact bones and spongy bones.
Term
Blood
Definition
fluid matrix ( plasma), it is still a connective tissue.
Term
Muscle Tissues
Definition
Most abundant tissue. major food user and major source of body heat.
Term
Skeletal Muscle
Definition
voluntary movement
Term
Smooth muscle
Definition
involuntary movement
Term
Cardiac muscle
Definition
involuntary contractions of heart
Term
Nervous Tissue
Definition
Neurons are the cells. the accessory cells are neuroglia.
Term
Neurons's 2 types of processes within
Definition
dendrites, which receive and transfer messages. Axons transfer messages away from cell body.
Term
Neurons's functions
Definition
relay info about interior and exterior enviroment. relay info from on part of the body to another.
Term
Nerve defination
Definition
a cluster of processes belonging to several neurons. Conducts messages from CNS ( brains/ spinal cord) and from sensory receptors back to the CNS.
