What is the primary function of the sensory system in animals?
A
To detect and transmit information about external and internal stimuli to the central nervous system
B
To generate movement by contracting muscles
C
To produce hormones that regulate body functions
D
To digest and absorb nutrients from food
Verified step by step guidance1
Step 1: Begin by understanding the sensory system's role in animals. The sensory system is responsible for detecting stimuli from the environment (external stimuli) and within the body (internal stimuli). These stimuli can include light, sound, temperature, pressure, and chemical signals.
Step 2: Recognize that the sensory system transmits the detected information to the central nervous system (CNS). The CNS, which includes the brain and spinal cord, processes this information to generate appropriate responses.
Step 3: Compare the primary function of the sensory system with the other options provided in the question. For example, generating movement by contracting muscles is the function of the muscular system, not the sensory system.
Step 4: Similarly, producing hormones to regulate body functions is the role of the endocrine system, and digesting and absorbing nutrients is the function of the digestive system. These are distinct from the sensory system's role.
Step 5: Conclude that the correct answer is the option describing the sensory system's primary function: 'To detect and transmit information about external and internal stimuli to the central nervous system.'
