Study Notes

Epithelial Tissue Types and Functions

Ciliated cells in the respiratory and reproductive tracts facilitate movement of oocytes through the uterine tubes by beating their cilia.
Microvilli enhance absorption in the intestinal cells, increasing surface area for nutrient uptake.
Locations of specific epithelial cells include:
- Ciliated cells: bronchioles, auditory tubes, uterine tubes, and uterus.
- Microvilli: intestinal lining.

Pseudostratified Columnar Epithelium

Composed of a single layer of cells with varying heights, giving a stratified appearance due to nuclei at different levels.
Ciliated pseudostratified columnar epithelial cells are often associated with goblet cells that secrete mucus.
Found in lining of nasal cavity, sinuses, auditory tubes, pharynx, trachea, and bronchi.

Stratified Squamous Epithelium

Contains multiple layers of cells, with cuboidal basal cells flattening towards the surface.
Functions in protection, absorption, and secretion.
Common locations include sweat gland ducts, mammary glands, larynx, and male urethra.

Structural Differences in Epithelium

Simple epithelium allows effective movement of materials, with functions like diffusion in alveoli and filtration in kidneys.
Stratified epithelium serves protective functions, commonly found in areas subject to abrasion.
Squamous cells are thin for diffusion, while cuboidal and columnar cells are larger for secretion and absorption.

Connective Tissue Types

Dense Collagenous Connective Tissue:
- Collagen fibers aligned along the same direction, providing tensile strength.
- Located in tendons, ligaments, dermis, and organ capsules.
Dense Elastic Connective Tissue:
- Contains both collagen and elastin fibers; provides strength and elasticity.
- Found in elastic ligaments, blood vessels, and the vocal cords.
Adipose Connective Tissue:
- Minimal extracellular matrix, primarily stored fat cells for energy and insulation.
- Present in intervertebral disks and around joints.

Cartilage and Bone

Elastic Cartilage:
- Contains elastin fibers providing flexibility while maintaining shape.
- Located in external ears and epiglottis.
Bone:
- Hard matrix with organized layers; contains osteocytes in lacunae.
- Provides structural support and protection for organs, facilitates movement.

Blood Composition

Comprised of blood cells and a fluid matrix known as plasma.
Functions include transportation of gases, nutrients, waste, and immune response.
Located within blood vessels; white blood cells can exit to tissues.

Muscle Tissue Types

Skeletal Muscle:
- Striated fibers with multiple peripheral nuclei; voluntary control.
- Attached to bones, facilitates body movement.
Cardiac Muscle:
- Striated, branched fibers with a single central nucleus connected by intercalated disks; involuntary control.
- Found exclusively in the heart to pump blood.
Smooth Muscle:
- Non-striated, tapered cells with a single nucleus; involuntary control.
- Regulates organ size and movement within hollow organs like the stomach and intestines.

Nervous Tissue Components

Composed of neurons, which conduct electrical impulses, and neuroglia, which support and protect neurons.
Neurons consist of:
- Cell Body: Contains the nucleus and organelles for basic functions.
- Dendrites: Receive stimuli for electrical changes.
- Axon: Conducts impulses away from the cell body.
Multipolar neurons transmit information and integrate signals.
