Lab Tissue Identification and Organ Systems

These flashcards cover key concepts and definitions related to lab activities, tissue identification, and organ systems.

Total magnification

Calculated as ocular power multiplied by objective power; for example, 10× × 40x = 400×.

Mitochondria

Organelles responsible for ATP production.

Rough ER

Endoplasmic reticulum involved in protein synthesis.

Nucleus

Contains genetic information and controls cell activities.

Lysosome

Organelle responsible for digestion within the cell.

Mitosis

Cell division that results in two identical diploid cells.

Meiosis

Cell division that results in four haploid gametes.

Simple squamous epithelium

A tissue type found in the lungs, facilitating diffusion.

Stratified squamous epithelium

A tissue type in the skin that provides protection.

Simple cuboidal epithelium

Tissue found in kidney tubules, involved in secretion.

Pseudostratified ciliated columnar epithelium

Tissue type found in the trachea, involved in secretion and movement.

Transitional epithelium

Tissue type in the bladder that allows for stretch.

Areolar tissue

A connective tissue under epithelia that cushions organs.

Dense regular connective tissue

Found in tendons and ligaments, providing tensile strength.

Dense irregular connective tissue

Located in the dermis, offering multidirectional strength.

Elastic connective tissue

Allows for stretch and recoil, found in arteries.

Anatomy

The study of the structure of body parts.

Physiology

The study of the function of body parts.

Skeletal system

Composed of bones and joints, providing support and movement.

Muscular system

Consists of muscles that facilitate movement and heat generation.

Nervous system

Includes the brain and spinal cord, controlling and coordinating body functions.

Cardiovascular system

Composed of the heart and blood vessels, responsible for transportation.

Respiratory system

Involves the lungs and trachea, facilitating gas exchange.

Digestive system

Includes the stomach and intestines, responsible for nutrient absorption.

Anatomical position

Standard position of the body: standing, facing forward, arms at sides, palms forward.

Epidermis layers

Layers of the skin from deep to superficial: basale, spinosum, granulosum, lucidum, corneum.
