Problem 15Chapter 4, Problem 15
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 guidance1
Step 1: Understand the components mentioned in the problem: axons, dendrites, and a cell body. These are structural features of certain types of cells.
Step 2: Recall that axons and dendrites are extensions of neurons, which are the primary cells of nervous tissue. The cell body (soma) contains the nucleus and organelles of the neuron.
Step 3: Review the characteristics of the other tissue types: muscle tissue is composed of muscle fibers, connective tissue contains cells like fibroblasts and extracellular matrix, and epithelial tissue consists of tightly packed cells forming layers.
Step 4: Recognize that only nervous tissue contains cells with axons, dendrites, and a cell body, which are essential for transmitting electrical signals.
Step 5: Conclude that the correct answer is nervous tissue, as it uniquely features cells with axons, dendrites, and a cell body.

Key Concepts
Here are the essential concepts you must grasp in order to answer the question correctly.
Neurons and Nervous Tissue
Neurons are specialized cells in nervous tissue responsible for transmitting electrical signals. They have unique structures such as axons, dendrites, and a cell body that facilitate communication within the nervous system.

The Neuron
Axons and Dendrites
Axons are long projections that carry impulses away from the neuron's cell body, while dendrites are branched extensions that receive signals from other neurons. Together, they enable the transmission and reception of nerve impulses.

Tissue Types in the Body
The body has four main tissue types: nervous, muscle, connective, and epithelial. Each has distinct cell structures and functions; for example, muscle tissue contracts, connective tissue supports, and epithelial tissue covers surfaces.
