Ch 5 Muscle TissueNervous Tissue
Three types of Muscle Tissue:• Skeletal • Smooth• Cardiac
Muscle tissues can CONTRACT when stimulated, thereby causing body movement
Skeletal Muscle Tissue• Attached to bone• Controlled consciously• Thread-like cells are striated (light-dark)• Cells are multinucleated
Ex. All body muscle which allows movement

Smooth Muscle Tissue• Involuntary Actions- not conscious• Short, spindle shaped cells• NOT striated• Single nucleus/cell
Ex. Walls of hollow organs (stomach, intestine, uterus, blood vessels, urinary bladder)

Cardiac Muscle Tissue• ONLY in the Heart• Involuntary movement• Cells STRIATED and BRANCHING• One nucleus/cell• Cells joined end-to-end like boxcars
– Intercalated disc=area where cells attach to each other
Nervous Tissue
• Brain• Spinal Cord• Peripheral Nerves
Coordinate, Regulate and Integrate many body functions.
Nerve Cells (Neurons)• Sense changes in their surroundings• Transmit impulses along cytoplasmic
extensions (processes) to:–Other neurons–Muscles–Glands
Neuroglial Cells
• Support & Bind Nervous Tissue• Phagocytic• Supply nutrients to Neurons
(connecting neurons to blood supply)
Epithelial Membranes• Epithelial tissue and Connective
tissue that form sheet-like membranes that cover body surfaces and line body cavities (a type of ORGAN)
Three types of Epithelial Membranes:Serous, Mucous, and Cutaneous
• Serous Membranes:–Line cavities that lack openings to
outside & cover their organs•Thoracic Cavity•Abdomenopelvic Cavity
–Secretes serous fluid•Lubricates surfaces
Mucous Membranes• Lines Cavities and Tubes that OPEN
to OUTSIDE of body• Oral Cavity• Nasal Cavity• Digestive, Respiratory, Urinary and
Reproductive Tubes
Cutaneous Membrane
•SKIN
Connective Tissue Membrane
•Synovial Membrane–Lines Joints
