Anatomy Cells

Pseudostratified columnar epithelial tissue is characterized by its unique appearance of multiple layers due to the varying heights of its cells. It is commonly found lining the upper respiratory tract and portions of the male reproductive tract, where it secretes mucus and aids in the movement of mucus by ciliary action. This type of tissue is distinct from simple squamous, stratified squamous, and simple cuboidal epithelial tissues in terms of its structure and function.

The correct answer is Simple Columnar (Epithelial Tissue) as it is characterized by elongated rectangular cells with a single nucleus near the base of the cell. Simple Columnar epithelium is commonly found in the small intestine where it aids in secretion and absorption.

The description of squarish cells with a central nucleus aligns with Simple Cuboidal epithelial tissue. Stratified Squamous is more layered, Adipose tissue stores fat, and Smooth Muscle tissue is elongated and spindle-shaped.

Simple Squamos (Epithelial Tissue) is the correct answer as it specifically fits the description provided in the question. Connective Tissue, Muscle Tissue, and Nervous Tissue do not consist of thin, flat, irregular cells each with one central nucleus.

Stratified cuboidal epithelium is characterized by multiple layers of cube-shaped cells, providing protection and limited secretion. It is most commonly found in the sweat gland ducts as well as in the ovaries and testes.

The correct answer is stratified squamous (epithelial tissue) because it is specifically described as having multiple layers of cells, with deep cuboidal or columnar cells becoming squamous near the apical surface, and fulfilling the functions of protecting against pathogens, resisting abrasion, and retarding water loss.

The correct answer is Transitional (Epithelial Tissue) because it is specifically designed to undergo expansion and contraction without losing its structural integrity, making it ideal for structures like the ureters, urinary bladder, and part of the urethra. Simple Squamous, Stratified Squamous, and Pseudostratified Columnar epithelial tissues do not have the same properties that allow them to stretch and permit distension in the same way as Transitional epithelial tissue.

Areolar (Loose Connective Tissue) fits the description provided in the question perfectly, making it the correct answer.

Blood is classified as connective tissue due to its function of connecting and supporting other tissues in the body through transport and communication.

Bone is the correct answer because it is the hardest type of connective tissue that contains calcium salts and chondroitin sulfate, providing physical support, protection, leverage, and mineral storage. Muscle, adipose tissue, and cartilage do not possess these characteristics.

Dense Regular (Connective Tissue) is characterized by its parallel arrangement of collagen fibers, which provides strength and is commonly found in tendons and ligaments. Dense Irregular (Connective Tissue) has a more random arrangement of collagen fibers, adipose tissue is primarily fat storage, and cartilage is a different type of connective tissue not described in the question.

Elastic cartilage is a type of connective tissue that has specific characteristics as mentioned in the question, making it the correct answer. Dense regular connective tissue, adipose tissue, and areolar connective tissue have different structures and functions compared to elastic cartilage, making them incorrect choices for this question.

Fibrocartilage is the correct answer because it contains chondrocytes among collagen fibers, absorbs shock, provides support, and is not enclosed in a perichondrium. Hyaline Cartilage lacks the collagen fibers among its chondrocytes, Adipose Tissue serves primarily as a fat storage area, and Dense Regular Connective Tissue does not have the same shock-absorbing properties as Fibrocartilage.

Hyaline cartilage is the most abundant type of cartilage and has a glossy, bluish-white appearance. It serves as the matrix for bone development and provides friction-free movement at joints. The incorrect answers, fibrocartilage, elastic cartilage, and fibrous cartilage, are other types of cartilage found in the body, but they do not match the description provided in the question.

Cardiac muscle tissue fits all the characteristics mentioned such as being found in the heart, having striations, involuntary contractions, and being excitable. Skeletal muscle tissue is also striated, but its contractions are voluntary. Smooth muscle tissue lacks striations. Adipose tissue is a type of connective tissue primarily involved in fat storage and does not match the characteristics mentioned.

Smooth muscle tissue is located in the walls of various organs such as the stomach, bladder, and uterus, as well as in blood vessels. Its unique characteristics include being non-striated and having involuntary contractions, distinguishing it from skeletal and cardiac muscle tissues.

Neurons and neuroglia together make up the nervous tissue, which is responsible for detecting stimuli and transmitting nerve signals.

The correct answer is Stratified Columnar (Epithelial Tissue) because it fits the description of being present in multiple layers of long, rectangular cells found specifically in limited regions of the body.

Dense Irregular (Connective Tissue) fits the description provided in the question as it consists of collagen fibers arranged randomly, providing strength for unpredictable stresses, and is found in locations mentioned. Loose Connective Tissue has fibers loosely arranged and is not suitable for resisting unpredictable stresses. Dense Regular (Connective Tissue) has collagen fibers arranged parallel to each other which provide strength for predictable stresses. Adipose (Fat) Tissue is a type of loose connective tissue that stores fat and provides cushioning rather than strength.

Elastic (Connective Tissue) is the correct answer because it specifically fits the description provided in the question. Dense Regular Connective Tissue, Adipose Tissue, and Hyaline Cartilage do not match all the characteristics mentioned in the question.
