Study Notes

Types of Tissues

Tissues are composed of similar cells functioning together.
Four primary types of human tissues:
- Connective Tissue: Binds and supports body parts.
- Muscular Tissue: Responsible for movement.
- Nervous Tissue: Receives stimuli and conducts impulses.
- Epithelial Tissue: Covers surfaces and lines cavities.

Connective Tissue

Connective tissue varies in structure and function, composed of:
- Specialized cells.
- Ground substance.
- Protein fibers.
Two main types:
- Fibrous Connective Tissue
- Specialized Connective Tissue:
  - Supportive: Includes cartilage and bone.
  - Fluid: Includes blood and lymph.

Types and Functions of Fibrous Connective Tissue

Loose Fibrous Connective Tissue:
- Contains space, found in lungs and urinary bladder.
- Functions as protective covering for organs.
Dense Fibrous Connective Tissue:
- Collagen fibers packed tightly, found in tendons and ligaments.
- Connects muscles to bones and bones to each other.
Cartilage:
- Solid yet flexible matrix, located in nose and ears.
- Provides support and protection.
Bone:
- Rigid matrix forms the human skeleton.
- Supports and protects organs, facilitates movement.
Blood:
- Comprised of blood cells and plasma.
- Functions in transport of substances.
Lymph:
- Derived from tissue fluid.
- Balances fluid, ions, and pH in the body.

Muscular Tissue

Muscular tissue enables internal and external body movement, also contributes to heat production.
Composed of muscle fibers containing actin and myosin proteins for contraction.
Three muscle types:
- Skeletal Muscle:
  - Attached to bones or via tendons, voluntary control.
  - Striated, multi-nucleated.
- Smooth Muscle:
  - Found in blood vessels and digestive tract, involuntary control.
  - Non-striated, single nucleus.
- Cardiac Muscle:
  - Exclusively in the heart, involuntary control.
  - Striated and branched cells, does not tire easily.

Nervous Tissue

Comprised of neurons and neuroglia.
Neurons conduct nerve impulses and have three parts:
- Dendrites: Receive signals.
- Cell Body: Contains nucleus and cytoplasm.
- Axon: transmits impulses, often covered in myelin.
Neuroglia: Support and nourish neurons, outnumber neurons significantly.

Epithelial Tissue

Composed of tightly packed cells forming continuous layers.
Functions:
- Covers surfaces and lines cavities.
- Protective and involved in secretion, absorption, and filtration.
Types based on layers:
- Simple Epithelium: One layer (e.g., squamous, cuboidal, columnar).
- Stratified Epithelium: Multiple layers.
Cell shapes:
- Squamous: Flat cells.
- Cuboidal: Cube-shaped cells.
- Columnar: Rectangular cells.

Body Cavities

The human body has two main cavities:
- Ventral Cavity: Contains thoracic, abdominal, and pelvic cavities.
  - Thoracic Cavity: Houses lungs and heart, separated from the abdomen by the diaphragm.
  - Abdominal Cavity: Contains digestive organs like stomach and intestines.
  - Pelvic Cavity: Houses rectum, bladder, and reproductive organs.
- Dorsal Cavity:
  - Cranial Cavity: Contains the brain.
  - Vertebral Canal: Houses the spinal cord.
