Document Summary
Cells tissues organs organ systems. Epithelial tissue: covers the body, lines the organs, & acts as a protective barrier, one side is always bound to basement membrane: underlying supportive surface, other side faces air, environment or fluids. 3 types of epithelium: simple 1 layer of cells, stratified multiple layers of cells, glandular absorb or secrete chemicals, cells at the exposed surface. Connective tissue (ct: supports & binds other tissues, 3 kinds of ct fibers. Reticular collagen & continuous with collagenous fibers: examples of connective tissue. Blood since it has an extensive extracellular matrix. Adipose tissue loose connective tissue that stores fats. Muscle tissue: skeletal responsible for voluntary movements. Also called striated muscle: smooth responsible for involuntary movements. Lacks striations = smooth: cardiac heart muscle. Nervous tissue: functional unit is the neuron or nerve cells, sense stimuli & transmit signals across the body. Transmit signals to other neurons, glands, muscles, & brain: 2 important systems.
