General Characteristics of Muscle Tissue
Function
• movement
Location
• attached to bones, in the walls of hollow organs, heart
3 main types
• Skeletal
• Smooth
• Cardiac
Distinguishing characteristics
• Contractile
• Fibers pull at the attached end to move body parts

Skeletal Muscle - Characteristics• Most abundant type found in
the body• Striated• Voluntary• Long, nonbranching cylindrical
cells• Multiple nuclei along
perimetersLocation
• Found around cartilage and bone
• Attach muscles to the skeleton

Cardiac Muscle - Key Characteristics• Weak striations• Involuntary• Cylindrical, branching
cells• Have intercalated disks
at end of cells• Centrally located nuclei• Once differentiated -
does not go through mitosis (aka - reproduce)
Location• Heart

Smooth Muscle -Key Characteristics• Involuntary
• Lack striations
• Single, centrally located nuclei
• Cells shorter than skeletal tissue and spindle shaped
• Used in the contraction of the bladder
• Peristalsis of the digestive system
• Constricts or dilates blood vessels
Location
• Found in walls of visceral organs (stomach, esophagus, uterus)

General Characteristics of Nervous TissueFunction
• transmit impulses for coordination, regulation, integration, & sensory reception
Location
• brain, spinal cord, nerves
Characteristics
• cells connect to each other & other body parts
• Cells contain a single nuclei
• Cells are called neurons
• Highly branched
• May have a covering called myelin
• Can’t reproduce once differentiated

Neurons in CNS
• Sense changes in the surroundings
• Transmit impulses along nerve fibers
• Coordinate, regulate, & integrate body functions
• Locations in the body
– Brain
– Spinal Cord

Neuroglial Cells
• Support and bind components of nervous tissue
• Phagocytosis
• Supply nutrients to neurons
• Able to reproduce
