Advanced Cellular and Tissue Biology Quiz

Smooth muscle is characterized by being involuntary and lacking striations, unlike skeletal muscle which is voluntary and striated.

Goblet cells are a type of epithelial cell that secrets mucus to protect and lubricate the lining of the intestines and respiratory tract.

Epithelial tissue is characterized by its close-packed cells, lack of blood vessels, and lack of nerve fibers. The basement membrane is a defining feature that separates epithelial tissue from the other tissue types mentioned.

Simple squamous epithelium is characterized by a single layer of flattened cells, making it ideal for functions such as diffusion and filtration. Stratified squamous epithelium consists of multiple layers of flat cells. Simple columnar epithelium is a single layer of tall cells, while pseudostratified columnar epithelium appears to be stratified but is actually a single layer of cells with varying heights.

Stratified epithelium is made up of multiple layers of cells stacked on top of each other. This arrangement provides protection and support to underlying tissues.

Epithelial tissue is responsible for forming glands in the body by secreting hormones, enzymes, and other substances. Nervous, muscular, and connective tissues serve different functions in the body.

The correct answer is digestive because this tissue is typically found in organs such as the stomach, small intestine, and large intestine where the process of digestion takes place.

Simple glands have ducts that do not extensively branch out, making it easier for secretion to be released.

Smooth muscle is responsible for the movement of food through the digestive tract due to its involuntarily contracting and relaxing nature, helping to push food along the digestive pathway.

Endocrine glands release their secretions directly into the blood stream to be carried to specific target organs or tissues in the body.

Pseudostratified columnar epithelium is known for its function in transportation due to the presence of cilia, which are hair-like structures that aid in moving substances along the epithelial surface.

Dense irregular elastic connective tissue is found in large arteries due to the need for the arteries to stretch and recoil with the pulsatile flow of blood. It is not found in the skin, lungs, or muscles as these areas do not require the same level of elasticity and support.

Adipose tissue primarily serves as a form of insulation for the body as well as a site for storing excess energy in the form of fat.

Cell connections like gap junction, tight junction, and plasmodesmata have different functions and are not solely responsible for preventing cells from coming apart. Desmosomes specifically serve this purpose by anchoring adjacent cells together.

Reticular tissue is a type of connective tissue that provides structural support in organs such as the lymph nodes, bone marrow, and spleen, where it forms the stroma. Therefore, the correct answer is lymphatic tissue.

Labile cells are cells that are continuously dividing and replacing themselves throughout life. Examples include skin cells, but not muscle, bone, or nerve cells.

Cartilage is a type of connective tissue that possesses cells located in lacunae, proteoglycans in ground substance, and a perichondrium on the surface. The absence of collagen fibers and the ability to heal rapidly after injury are also characteristics of cartilage.

Epithelial tissue is specialized in secretion and absorption of molecules due to its tightly packed cells forming a protective barrier.

The four primary tissue types are epithelial, connective, muscle, and nerve. Each type of tissue serves specific functions in the human body.

The epidermis is indeed nourished by blood vessels located in the dermis, providing essential nutrients to the outermost layer of the skin.

The stratum lucidum is the second layer of the epidermis from the surface, followed by stratum granulosum, stratum spinosum, and stratum basale. Each layer plays a crucial role in the skin's structure and function.

Keratinization is the process by which cells develop keratin, a tough protein that helps to protect the skin from damage and abrasion. Ossification is the process of bone formation, Glycolysis is the metabolic process of breaking down glucose for energy, and Photosynthesis is the process by which plants convert light energy into chemical energy.

The correct answer is 'Head' because proportionally, children have larger heads compared to their bodies, with the head typically comprising 15% of their total body weight. This percentage decreases to 9% in adults as their bodies grow and proportions change.

Third-degree burns destroy the sweat glands, so the ability to sweat is reduced or lost. The other conditions listed commonly occur as a result of third-degree burns.

The correct scientific term for red blood cells is erythrocyte, while leukocyte refers to white blood cells, thrombocyte refers to platelets, and neutrophil is a type of white blood cell.
