Which of the following is a primary feature of nervous tissue?

• A. Striated muscle fibers for contraction
• B. Neurons specialized for transmitting electrical impulses
• C. Chondrocytes embedded in a gel-like matrix
• D. Adipocytes storing triglycerides

Answer: (B)

Verified step by step guidance

1. Step 1: Understand the question by identifying the key focus, which is to determine the primary feature of nervous tissue. Nervous tissue is specialized for communication and control within the body.
2. Step 2: Review the characteristics of nervous tissue. Nervous tissue primarily consists of neurons and supporting cells (glial cells). Neurons are specialized for transmitting electrical impulses, which is the key function of this tissue.
3. Step 3: Analyze the options provided: (1) Striated muscle fibers for contraction are characteristic of muscle tissue, not nervous tissue. (2) Neurons specialized for transmitting electrical impulses are the defining feature of nervous tissue. (3) Chondrocytes embedded in a gel-like matrix are characteristic of cartilage, which is connective tissue. (4) Adipocytes storing triglycerides are characteristic of adipose tissue, another type of connective tissue.
4. Step 4: Eliminate the incorrect options based on their association with other tissue types. This leaves the correct answer as 'Neurons specialized for transmitting electrical impulses.'
5. Step 5: Conclude that the primary feature of nervous tissue is its ability to transmit electrical impulses through neurons, which allows for communication and coordination within the body.
