What type of matrix characterizes cartilage tissue?
Press to flip
A watery matrix resistant to compressive and tensile forces.
What is the primary function of connective tissue?
To bind and support other tissues in the body.
How is cardiac muscle tissue specialized in terms of control and structure?
It is striated, under involuntary control, and located in heart walls.
Why is blood considered an atypical connective tissue?
Because it is a liquid and lacks fibers in its extracellular matrix.
How do dense regular and dense irregular connective tissues differ in fiber arrangement?
Dense regular connective tissue has collagen fibers in a parallel arrangement, while dense irregular has fibers in different directions.
Explain the role of elastic fibers in dense elastic connective tissue.
They allow the tissue to stretch and recoil.
What is the role of red marrow in bone tissue?
It is the site of blood cell production.
Identify the three types of cartilage and a distinguishing feature of each.
Hyaline: most abundant, supports and reinforces; Fibrocartilage: thick collagen fibers, resists compressive and tensile forces; Elastic Cartilage: more elastic fibers, allows flexibility.
What are the key functions of areolar connective tissue?
Supports and binds other tissues, holds body fluids, defends against infection, and stores nutrients as fat.
How do neurons differ from supporting cells in nervous tissue?
Neurons are excitable and send electrical impulses, while supporting cells are non-excitable and support neurons.
Name the types of cells found in connective tissue proper.
Fibroblasts and Fibrocytes
Describe the extracellular matrix of connective tissue.
Composed of ground substance, which holds interstitial fluid, and fibers such as collagen, elastic, and reticular fibers.
From which embryonic tissue are all connective tissues derived?
Mesenchyme
List the types of muscle tissue.
Skeletal Muscle, Cardiac Muscle, Smooth Muscle.
What are the main components of nervous tissue?
Neurons and supporting cells.
