Study Notes
Levels of Biological Organization
- Biological organization ranges from the lowest level (chemical) to the highest level (biosphere).
- Levels include: chemical, organelle, cell, tissue, organ, organ system, organism, population, community, ecosystem, and biosphere.
Types of Animal Tissue
- Four primary types of animal tissue: epithelial, connective, muscle, and nervous tissue.
- Each tissue type has distinct structures and functions.
Epithelial Tissue
- Composed of tightly packed cells that cover, line, and protect body surfaces.
- Classification types based on:
- Cell arrangement:
- Simple (single layer)
- Stratified (multiple layers)
- Pseudostratified (appears layered but is not)
- Cell shape:
- Squamous (flat)
- Cuboidal (cube-shaped)
- Columnar (column-shaped)
- Cell arrangement:
Connective Tissue
- Composed of various cells and an extracellular matrix that connects, protects, and supports different body parts.
- Types of connective tissue include:
- Bone
- Cartilage
- Dense connective tissue
- Loose connective tissue
- Blood
Muscular Tissue
- Made of highly specialized muscle cells responsible for contraction and movement.
- Three types of muscular tissue:
- Skeletal muscle (voluntary, striated)
- Cardiac muscle (involuntary, striated)
- Smooth muscle (involuntary, non-striated)
Nervous Tissue
- Composed of neurons that transmit electrochemical signals.
- Contains supporting cells known as glial cells, which provide support, protection, and insulation for neurons.
