Example Questions
Example Question #631 : Ap Biology
What is the function of collagenous fibers?
Selective absorption of extracellular fluid
Act as scaffolding for cells
Allow for the recoil of organs
Bind bones together and provide structural support
Bind bones together and provide structural support
Collagenous fibers are composed primarily of collagen. Collagenous fibers bind bones together and connect different tissues to one another. Examples of collagenous fibers include tendons, cartilage, and blood vessels.
Example Question #632 : Ap Biology
Which of the following is not an example of a collagenous fiber in connective tissue?
Ligaments
Tendons
Stratified epithelium
Blood vessels
Stratified epithelium
Collagenous fibers connect tissue types and bind elements of the musculoskeletal system to one another. Types of collagenous fibers in connective tissue include blood vessels, ligaments, and tendons. Stratified epithelium is comprised of layers of epithelial cells, which function as a covering/lining to a body structure that is subject to lots of friction.
Example Question #572 : Cellular Biology
What is the main function of elastic fibers in connective tissue?
Act as scaffolding for cells
Aid in the secretion of substances
Bind bones together
Allow for tissue and organs to recoil
Allow for tissue and organs to recoil
Elastic fibers are a type of fiber within the connective tissue category. These types of fibers are made up of the protein elastin and they allow tissues and organs to recoil and oppose tearing forces.
Example Question #573 : Cellular Biology
In the connective tissue, what is the function of reticular fibers?
To bind bones together
Allow for the transmission of chemical signals
Contract to create movement
Provide a scaffolding for cells
Provide a scaffolding for cells
Reticular fibers are composed of collagen and form thin mesh networks that supports cells, tissues, and organs. The reticular meshwork also acts as a scaffold for other structures to anchor into.
Example Question #11 : Understanding Connective Tissue
Which of the following is not a function of connective tissue in the human body?
Transmission of electrical and chemical signals
Allows for the diffusion of nutrients and oxygen
Acts as a starting point for immune responses
Resistance of stretching and tearing forces
Transmission of electrical and chemical signals
In the human body, connective tissue has a variety of functions that allows proper function and survival. These functions include elasticity to resist tearing and stretching forces, loose tissue and ground substance that allow for the diffusion of nutrients and oxygen, and immune cells that can activate to protect the body.
Example Question #12 : Understanding Connective Tissue
In humans, are all types of connective tissue fibrous?
No, not all connective tissue is fibrous, including blood and adipose tissue
Yes, all connective tissue contains all three types of fibers (collagenous, reticular, and elastic)
Yes, all connective tissue contains at least one type of fiber (collagenous, reticular or elastic)
No, not all connective tissue if fibrous because in some areas of the body the ground substance degrades fibers
No, not all connective tissue is fibrous, including blood and adipose tissue
In the human body, not all types of connective tissue contain fibers. Examples of non-fibrous connective tissues are blood, adipose tissue, and bone which are made of plasma and cells, fat, and mineralized extracellular matrix, respectively.
Example Question #13 : Understanding Connective Tissue
What is the purpose of connective tissue in the human body?
Lines the cavities and surfaces of organs in the body
Transmits information through electrical signals
Supports and connects different organs and tissues in the body
Produces motion
Supports and connects different organs and tissues in the body
Connective tissue is a category of tissue in the human body that supports and connects different organs and tissues in the body. Other tissue categories in the human body include epithelial, which lines the cavities and surfaces of the organs in the body, muscle, which contracts to produce motion, and nervous tissue, which transmits information through electrical and chemical signals.
Example Question #14 : Understanding Connective Tissue
What describes a major difference between cartilage and bone?
Cartilage is composed of collagen and salts
Cartilage does not have blood vessels or nerves, while bone does
Bone is part of the skeletal system, while cartilage is not
Cartilage secretes a matrix
Bone provides structure to the human body
Cartilage does not have blood vessels or nerves, while bone does
Cartilage also performs a structural function, but it is more flexible than bone. Furthermore, it doesn't have nerves or blood vessels. This explains why a broken bone heals quite well (sometimes the broken bone becomes stronger than it was before) while cartilage does not heal/regenerate nearly as fast. They both secrete matrices, and are made up of collagen and calcium salts.
