Study Notes
Cell Cycle Phases
- Interphase: The cell is actively growing and performing normal functions; preparation for division.
- Prophase: The nuclear envelope disintegrates; chromosomes become visible but remain unassigned in position.
- Metaphase: Chromosomes align along the mitotic spindle at the cell's equatorial plane.
- Anaphase: Sister chromatids are pulled apart to opposite poles of the cell.
- Telophase: Chromosomes have separated and begin to de-condense; nuclear envelopes reform around each set.
Cellular Structures
- Cell: The fundamental structural and functional unit of life.
- Nucleus: Houses chromatin; undergoes division during mitosis.
- Plasma membrane: A double-layered membrane that encloses the cell, controlling entry and exit of substances.
- Nuclear envelope: A double-layered membrane that surrounds and protects the nucleus.
Anatomical Planes
- Sagittal plane: Divides the body into right and left portions.
- Midsagittal plane: Cuts the body into equal right and left halves along the midline.
- Frontal (coronal) plane: Divides the body into anterior (front) and posterior (back) sections.
- Transverse plane: Splits the body into superior (upper) and inferior (lower) sections.
Anatomical Directions
- Proximal: Indicates that a body part is closer to the point of attachment than another part (e.g., knee to foot).
- Lateral: Refers to a position further away from the midline of the body (e.g., shoulder to sternum).
- Inferior: Denotes a position lower than another structure (e.g., abdomen to thorax).
Tissue Types
- Simple columnar epithelium: A type of tissue with taller, column-like cells.
- Simple cuboidal epithelium: Composed of cube-shaped cells.
- Stratified squamous epithelium: Multiple layers of flat cells; provides protection.
- Pseudostratified columnar epithelium: Appears layered due to differing cell heights but is a single layer.
- Mesenchyme: A form of connective tissue found in the embryo.
- Hyaline cartilage: Provides support and flexibility; lacks visible fibers.
- Areolar tissue: A loose connective tissue that supports and binds other tissues.
- Adipose tissue: Stores fat; serves as insulation and energy reserve.
- Blood: Transports nutrients, waste, and gases throughout the body.
Cellular Components
- Erythrocytes: Red blood cells responsible for oxygen transport.
- Leukocytes: White blood cells that play roles in immune defense.
- Collagen: A key extracellular matrix protein providing strength to tissues.
- Osseous tissue: Also known as bone tissue; provides structure and support.
- Lacunae: Small cavities within tissue, often found in bone or cartilage.
- Lamellae: Concentric layers of bone matrix in osseous tissue.
- Chondrocyte: A cell found in cartilage responsible for maintaining cartilage matrix.
Microscope Components
- Ocular Lens: The eyepiece through which an object is viewed; typically provides 10x magnification.
- Objective Lens: Shorter lenses that provide varying levels of magnification (e.g., 4x, 10x, 40x).
- Stage: The platform that holds the slide being observed.
- Mechanical Stage: A device that allows precise movement of the slide for better viewing.
- Iris Diaphragm: Regulates the amount of light that reaches the specimen.
- Condenser: Focuses light onto the specimen to improve clarity.
- Rotating Nosepiece: Holds multiple objective lenses; allows for easy switching.
- Course Adjustment Knob: Used to make large adjustments to focus the image.
- Fine Adjustment Knob: Used for precise focus adjustments.
- Total Magnification: Calculated by multiplying the power of the ocular lens by the power of the objective lens.
