Question

sensory stimuli enter the spinal cord via
multiple choice
interneurons
efferent effectors
efferent axons
afferent axons
sensory receptors

Explanation:

• Interneurons: These are located within the central nervous system (CNS) and are involved in connecting neurons within the CNS, not in bringing sensory stimuli into the spinal cord.
• Efferent effectors: Effectors are the target organs (like muscles or glands) that respond to motor commands. They are not involved in the entry of sensory stimuli.
• Efferent axons: Efferent (motor) axons carry signals away from the CNS to effectors, not sensory signals into the spinal cord.
• Afferent axons: Afferent (sensory) axons carry sensory stimuli from sensory receptors towards the CNS (including the spinal cord).
• Sensory receptors: While they detect sensory stimuli, the actual entry into the spinal cord is via the afferent axons that are connected to these receptors.

Answer:

afferent axons
