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.
- Skeletal Muscle:
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.
- Ventral Cavity: Contains thoracic, abdominal, and pelvic cavities.
