Textbook Question

Axons, dendrites, and a cell body are characteristic of cells located in
(a) Nervous tissue
(b) Muscle tissue
(c) Connective tissue
(d) Epithelial tissue

Verified step by step guidance

Step 1: Begin by identifying the structural components mentioned in the problem: axons, dendrites, and a cell body. These are parts of a specialized cell type known as neurons.

Step 2: Recall the primary function of neurons. Neurons are responsible for transmitting electrical signals throughout the body, which is a key function of the nervous system.

Step 3: Understand the relationship between neurons and nervous tissue. Nervous tissue is composed of neurons and supporting cells (glial cells), and it is specialized for communication and signal transmission.

Step 4: Compare the characteristics of nervous tissue with the other tissue types listed in the options: muscle tissue (responsible for contraction), connective tissue (provides structural support), and epithelial tissue (covers surfaces and lines cavities). None of these other tissue types contain neurons with axons, dendrites, and cell bodies.

Step 5: Conclude that the correct answer is nervous tissue, as it is the only tissue type that contains neurons with the described structures.

Key Concepts

Here are the essential concepts you must grasp in order to answer the question correctly.

Nervous Tissue

Nervous tissue is specialized for the transmission of electrical signals throughout the body. It is primarily composed of neurons, which include axons, dendrites, and a cell body, and glial cells that support and protect neurons. This tissue is essential for communication between different parts of the body and plays a critical role in reflexes, sensory perception, and motor control.

Neurons

Neurons are the fundamental units of nervous tissue, responsible for carrying signals through electrical impulses. Each neuron consists of a cell body (soma), dendrites that receive signals, and an axon that transmits signals to other neurons or muscles. The unique structure of neurons allows for rapid communication and processing of information in the nervous system.

Tissue Types

Tissue types in the body are classified into four main categories: nervous, muscle, connective, and epithelial tissues. Each type has distinct structures and functions; for example, muscle tissue is involved in movement, connective tissue provides support and structure, and epithelial tissue covers surfaces. Understanding these categories helps in identifying the specific roles and characteristics of different cells and tissues.
