What are the two primary cell types in neural tissue, and what are their main functions?
Press to flip
Neurons, which carry information to and from the brain, and Neuroglia, which are supporting cells providing nutrients, insulation, and waste removal.
What role does smooth muscle play in the body?
Smooth muscle is involved in the function of hollow organs like the stomach and blood vessels, helping in movements such as peristalsis and vasoconstriction.
Describe the muscle types that are under involuntary control and where they are found in the body.
Smooth muscle, found in walls of hollow organs like the stomach, intestines, and blood vessels, and cardiac muscle, found only in the heart.
What are the characteristics and functions of transitional epithelium?
Transitional epithelium can stretch and return to its original shape, useful for organs like the bladder which expand and contract.
Explain the difference between voluntary and involuntary muscle control with examples.
Voluntary muscle control involves conscious control, as seen in skeletal muscles like the biceps. Involuntary muscle control operates without conscious control, as seen in smooth and cardiac muscles.
Identify the main functional differences between blood and bone within connective tissue.
Blood serves in transportation of nutrients, waste, and gases, while bone provides structural support and protection for the body's organs.
How do neurons transmit information?
Neurons transmit information through electrical and chemical signals to and from the brain.
What are the subtypes of fibrous connective tissue, and how do they differ?
The subtypes are Loose, Dense, and Reticular connective tissue. Loose connective tissue has a loose arrangement of fibers, Dense has tightly packed fibers, and Reticular has a network of reticular fibers.
Where is neuroglia found, and what are its primary functions?
Neuroglia is found in the nervous system and functions to support neurons by providing nutrients, insulation, and waste removal.
List the three main shapes of cells in simple epithelial tissue and their respective examples.
Simple Squamous (flat cells, e.g., lining of blood vessels), Simple Cuboidal (cube-shaped cells, e.g., kidney tubules), and Simple Columnar (tall, column-like cells, e.g., lining of the stomach).
Name the different types of cartilage found in connective tissue.
Hyaline cartilage, Elastic cartilage, and Fibrocartilage.
Why is stratified squamous epithelium suited for protection?
Stratified squamous epithelium has multiple layers, which provide a durable barrier against friction, pathogens, and physical abrasions.
Describe the structure and function of skeletal muscle.
Skeletal muscle is attached to bones and is under voluntary control, enabling movements like walking, talking, and other body activities.
What are the primary differences between hyaline, elastic, and fibrocartilage?
Hyaline cartilage provides smooth surfaces for movement at joints, elastic cartilage provides flexibility, and fibrocartilage provides strong support and withstands heavy pressure.
What distinguishes simple epithelial tissue from stratified epithelial tissue?
Simple epithelial tissue consists of a single layer of cells, while stratified epithelial tissue consists of multiple layers of cells.
