Study Notes

Tissues

Tissues are groups of similar cells that work together to perform a specific function
Tissues combine to form organs
Organs work together in organ systems

Types of tissues

Epithelial tissue covers exposed surfaces, lines internal passageways, and produces glandular secretions.
Connective tissue fills internal spaces, provides structural support, stores energy, and transports substances.
Muscle tissue contracts to produce active movement.
Nervous tissue transmits electrical impulses to rapidly sense the internal and external environment, processing information and controlling responses.

Connective tissue types

Connective tissue proper
- Loose fibers are loosely packed, creating an open framework
- Dense fibers are densely packed
Fluid connective tissues
- Blood flows within the cardiovascular system
- Lymph flows within the lymphatic system
Supporting connective tissues
- Cartilage is solid and rubbery
- Bone is solid and crystalline

Cartilage types

Hyaline Cartilage is the most common type, found in the nose, trachea, and ribs. It provides stiff but flexible support and reduces friction.
Elastic Cartilage is found in the ears and epiglottis. It is more flexible than hyaline cartilage and can return to its original shape after distortion.
Fibrocartilage is found in the intervertebral discs and menisci of the knee. It is the strongest type of cartilage and resists compression.

Membranes

Serous membranes line body cavities and cover organs. They are composed of a thin layer of epithelium and connective tissue.
- Parietal layer lines the inner surface of the cavity.
- Visceral layer covers the outer surface of organs.
- Serous fluid reduces friction between the layers.
**Cutaneous membrane ** is the skin. It is made of stratified squamous epithelium and connective tissue. It is thick, waterproof, and usually dry.
Synovial Membranes line joint cavities and are composed of areolar connective tissue and a thin epithelial layer. They produce synovial fluid, which lubricates the joint and allows smooth movement.

Muscle Tissue

Specialized for contraction.
Composed of long, slender cells called muscle fibers.
Contraction is due to interactions between filaments of myosin and actin proteins.
Can be voluntarily controlled or primarily controlled by the nervous system (involuntary).

Types of Muscle Tissue

Skeletal muscle tissue is striated and voluntary.
Smooth muscle tissue is nonstriated and involuntary. It is found in the walls of blood vessels, hollow organs, and the digestive, respiratory, urinary, and reproductive tracts.
Cardiac muscle tissue is found only in the heart. It is striated and involuntary.

Nervous Tissue

Specialized for transmitting electrical impulses.
Most concentrated in the brain and spinal cord.
Rapidly senses internal or external environment.
Processes information and controls responses.
