Tissues Flashcards
What of the following is NOT a type of connective tissue?
Stratified squamous epithelium
Connective tissues include:
adipose tissue, blood, and cartilage
Which type of epithelial tissue is specialized for absorption and secretion, and is
found lining the intestines?
Simple columnar epithelium.
Simple columnar epithelium lines the intestines and is specialized for absorption and secretion.
What is the primary function of muscle tissue?
Muscle tissue is primarily responsible for movement and contraction in the body.
Which of the following statements is true about nervous tissue?
It is composed of neuron’s and neuroglia.
Nervous tissue consists of neuron’s, which transmit impulses, andneuroglia, which support and protect neuron’s.
Which of the following tissues is known for its ability to stretch and return to its original shape, commonly found in the urinary bladder?
Transitional epithelium
Transitional epithelium is found in the urinary bladder and is designed to stretch and return to its original shape.
Explain the difference between exocrine and endocrine glands and provide an example of each.
Exocrine glands secrete their products into ducts that lead to a specific location (e.g., sweat glands). Endocrine glands secrete hormones directly into the bloodstream (e.g., thyroid gland).
Describe the structure and function of simple squamous epithelium and give an example of where it is found in the body.
Simple squamous epithelium consists of a single layer of flat, thin cells. Its primary function is to allow for rapid diffusion and filtration. It is found in areas like the alveoli of the lungs and the lining of blood vessels (endothelium).
What are the three main components of connective tissue, and how do they contribute to the tissue’s function?
The three main components are cells (e.g., fibroblasts), fibers (e.g., collagen), and the extracellular matrix. Cells produce the fibers and matrix, fibers
provide strength and support, and the extracellular matrix fills the space between
cells, offering structural support and a medium for nutrient diffusion.
What is the significance of the extracellular matrix in connective tissues, and how does it vary among different types of connective tissue?
The extracellular matrix provides structural and biochemical support to the surrounding cells. It varies in composition (fibers and ground substance) depending on the type of connective tissue. For example, bone has a calcified matrix for rigidity, while blood has a fluid matrix (plasma) for circulation.
