Study Notes
Types of Human Tissues
- Human tissues are groups of cells working together for specific functions.
- Four primary tissue types exist: epithelial, connective, muscle, and nervous.
Epithelial Tissue
- Forms outer layers of organs (internal and external).
- Key functions: protection, absorption, secretion.
- Examples: skin (epidermis), digestive tract lining.
Connective Tissue
- Supports, binds, and protects tissues/organs.
- Subtypes:
- Loose connective: Provides elasticity (e.g., adipose tissue).
- Dense connective: Provides strength; resists tension (e.g., tendons, ligaments).
- Specialized connective: Includes bone (structural support), blood (nutrient/gas transport).
Muscle Tissue
- Enables movement through contraction.
- Three types:
- Skeletal muscle: Attached to bones; voluntary movement.
- Cardiac muscle: Found in the heart; pumps blood (involuntary).
- Smooth muscle: Found in hollow organs; involuntary movements (e.g., intestines, blood vessels).
Nervous Tissue
- Receives and transmits electrical signals.
- Components:
- Neurons: Nerve cells that carry signals.
- Glial cells: Support and protect neurons.
Tissue Cell Structure
- Cells vary in structure but share common components:
- Cell membrane: Lipid bilayer, regulates substance movement.
- Cytoplasm: Gel-like substance; houses organelles and facilitates reactions.
- Nucleus: Contains DNA; controls cellular activities, replication, and RNA synthesis.
- Organelles: Specialized structures:
- Mitochondria: Powerhouse, produces ATP.
- Endoplasmic reticulum (ER): Rough (protein synthesis), smooth (lipid synthesis).
- Golgi apparatus: Modifies, sorts, and packages proteins/lipids.
- Ribosomes: Synthesize proteins.
- Lysosomes: Digest waste and cellular debris.
- Peroxisomes: Break down fatty acids, detoxify.
- Cytoskeleton: Provides support, movement, and transport.
- Centrioles (animal cells): Involved in cell division.
- Vacuoles: Storage (nutrients, waste).
Types of Epithelial Tissue
- Categorized by cell shape and arrangement:
-
Cell Shape:
- Squamous: Flat, thin; diffusion and filtration (e.g., lungs, blood vessels).
- Cuboidal: Cube-shaped; secretion and absorption (e.g., kidneys, glands).
- Columnar: Tall, column-shaped; absorption and secretion (e.g., digestive tract).
-
Cell Arrangement:
- Simple: Single layer; absorption, secretion, filtration.
- Stratified: Multiple layers; protection.
- Transitional: Can change shape; stretching; (e.g., urinary bladder).
-
Cell Shape:
Types of Connective Tissue
- Diverse roles in support, binding, and protection.
- Subtypes:
- Connective tissue proper:
- Loose connective (areolar, adipose, reticular): Diverse functions.
- Dense connective (regular, irregular, elastic): Strength and support.
- Specialized connective:
- Cartilage (hyaline, elastic, fibrocartilage): Support and cushioning.
- Bone (osseous tissue): Support, protection, mineral storage.
- Blood: Transport.
- Connective tissue proper:
Types of Muscle Tissue
- Contraction and movement:
- Skeletal muscle: Voluntary movements.
- Cardiac muscle: Heart contractions.
- Smooth muscle: Involuntary movements in internal organs.
Types of Nervous Tissue
- Coordination and regulation of functions.
- Parts:
- Central Nervous System (CNS): Brain, spinal cord; Higher functions.
- Peripheral Nervous System (PNS): Somatic (voluntary movements), Autonomic (involuntary processes),Enteric( gastrointestinal tract)
- Parts:
