Study Notes
Cell Cycle
- The cell cycle has two major periods: Interphase and Cell Division
- Interphase: cell grows, carries out usual activities, and prepares for cell division
- Interphase consists of three subphases: G1 (vigorous growth and metabolism), S (DNA replication), and G2 (preparation for division)
- Cell division (mitotic phase): cell divides into two, consisting of Prophase, Metaphase, Anaphase, Telophase, and Cytokinesis
Tissues
Nervous Tissue
- Internal communication
- Found in brain, spinal cord, and nerves
- Doesn't regenerate
Muscle Tissue
- Contracts for movement
- Types: Skeletal (voluntary movement, locomotion, facial expression), Cardiac (involuntary control, propels blood into circulation)
Epithelial Tissue
- Forms boundaries between different environments
- Found on skin surface, lining of digestive tract, sensory organs, and glands
- Has polarity, regenerates quickly
- Shapes: Squamous, Cuboidal, Columnar
- Types:
- Simple Columnar (e.g., small intestine)
- Simple Squamous (e.g., alveoli in lungs)
- Stratified Squamous (e.g., skin, trachea)
- Pseudo-Stratified Columnar (e.g., trachea)
- Stratified Squamous Keratinized (e.g., skin with keratin)
Connective Tissue
- Supports and protects other tissues
- Types:
- Connective tissue proper:
- Loose connective tissue (e.g., Aerolar, Adipose, Reticular)
- Dense connective tissue (e.g., Dense Regular, Dense Irregular, Elastic)
- Supporting connective tissue:
- Cartilage (e.g., Hyaline cartilage)
- Connective tissue proper:
Understand the two major periods of the cell cycle, including interphase, where cell growth and preparation for cell division occur. Learn about the subphases of interphase, including G1 and S phases.
