Histology
Study of tissues
Four fundamental tissues are
Epithelial connective muscle and nervous issues
Epithelial cells function
Cover line and protect the body and its internal organs
Connective tissue is
Framework of body providing support and structure for the Organs
Nerve tissue is composed of
Neurons in contest connective tissue cells that are referred to as neuroglia
Muscle tissues have
Ability to contract or shorten
Voluntary muscle
Under conscious control. Skeletal muscles must work in pairs: the muscle that executes a given move it is the prime mover, whereas the muscle that produces the opposite movement is the antagonist. Other muscles known as synergist may work in cooperation with the prime mover
Involuntary muscle
Smooth muscle and cardiac muscle tissue
Cell
The basic unit of life and blocks of tissue and organs
Nucleus contains
Deoxyribonucleic acid or DNA and ribosomes are especially important in synthesis of proteins.
Mitosis
Necessary for growth and repair, DNA is replicated and distributed evenly to two daughter cells
