Lecture 7 Flashcards
Used to describe a group of cells found together in the body
Tissue
The cells within a tissue share a common
Embryonic origin
Four broad categories of tissues:
Epithelial
Connective
Muscle
Nervous
Microscopic study of tissue appearance, organization, and function
Histology
Three germ layers:
Ectoderm (outer)
Mesoderm (middle)
Endoderm (inner)
Ectoderm gives rise to:
Skin cells
Neurons
Pigment cells
Mesoderm gives rise to
Cardiac muscle Skeletal muscle Tubule cell of kidney Red blood cells Smooth muscle
Endoderm gives rise to:
Lung cell
Thyroid cell
Pancreatic cell
A thin layer or sheet of cells that covers the outside of the body, the organs, internal passageways, lining of moveable joint cavities
Tissue membrane
Two basic types of tissue membrane:
Connective tissue
Epithelial membranes
Connective tissue membranes include:
Synovial membranes
Epthelial membranes include:
Mucous membranes
Serous membranes
Cutaneous membranes
Formed solely from connective tissue
Encapsulate organs and line of joints
Connective tissue membrane
Type of connective tissue membrane that line the cavity of the freely moveable joint
Synovial membrane
Releases hyaluronan into the joint cavity
Fibroblasts
