Which of the following are the four basic types of tissues that the body contains?

Appeared in: RRB Staff Nurse Jaipur-6th June 2018

Explanation

The human body is composed of four fundamental or primary types of tissues: epithelial, connective, muscle, and nervous tissue.
Each tissue type has a unique structure and set of functions, and they combine in various ways to form all the organs and systems of the body.
Epithelial tissue provides covering and secretion, connective tissue provides support and connection, muscle tissue enables movement, and nervous tissue facilitates communication and control.

Option B: This option lists only sub-classifications of connective tissue (loose, dense, regular, irregular). It does not include the other three primary tissue types.
Option C: This option lists specific examples of tissues, not the four basic categories. Bone, cartilage, and adipose tissue are all types of connective tissue, and glands are derived from epithelial tissue.
Option D: This option incorrectly mixes two basic tissue types (muscle, connective) with specific subtypes. Cartilage is a type of connective tissue, and glandular tissue is a type of epithelial tissue.

Clinical Relevance

Nursing practice connection: This is primarily an exam-oriented knowledge point with limited direct bedside application, so retain Four basic types of body tissues as background academic context rather than a clinical decision trigger.
Understanding tissue types is fundamental to pathology. Cancers are classified based on their tissue of origin (e.g., carcinomas from epithelial tissue, sarcomas from connective tissue).
Knowledge of tissue types is essential for wound care. Healing involves the regeneration and repair of epithelial and connective tissues, and nurses monitor this process.
Histology, the study of tissues, helps in diagnosing diseases by examining tissue samples (biopsies) under a microscope.

How to Approach the Question

This is a factual recall question asking for a fundamental biological classification.
Identify the key phrase in the question: 'four basic types of tissues'.
Systematically evaluate each option to see if it lists the four primary, high-level categories.
Option A lists four distinct, major tissue groups.
Recognize that Options B, C, and D contain terms that are either subtypes (e.g., 'dense regular connective') or specific examples (e.g., 'bone', 'cartilage') of the basic categories.
Eliminate the options that list subtypes or examples, as they do not represent the four fundamental classifications.
