Which of the following best describes a characteristic of nervous tissue?
A
It primarily functions in contraction and movement.
B
It is specialized for the conduction of electrical impulses.
C
It stores large amounts of triglycerides.
D
It forms the outer protective layer of the body.
Verified step by step guidance1
Step 1: Begin by identifying the primary function of nervous tissue. Nervous tissue is specialized for communication within the body, primarily through the conduction of electrical impulses.
Step 2: Compare the given options to the known characteristics of nervous tissue. Eliminate options that do not align with its primary function.
Step 3: Evaluate the first option, 'It primarily functions in contraction and movement.' This describes muscle tissue, not nervous tissue.
Step 4: Evaluate the third option, 'It stores large amounts of triglycerides.' This describes adipose tissue, which is specialized for energy storage, not nervous tissue.
Step 5: Evaluate the fourth option, 'It forms the outer protective layer of the body.' This describes epithelial tissue, which forms protective barriers, not nervous tissue. The correct answer is the second option: 'It is specialized for the conduction of electrical impulses.'
