Question

based on the information in table 1, the student investigates a classmates patellar reflex. after watching the reflex in action, the student starts to design a new model to show this information. which pathway should the students model show that the signals in this reflex follow? a. knee strike → muscle b. knee strike → nerve → muscle c. knee strike → spinal cord → nerve → muscle d. knee strike → nerve → spinal cord → nerve → muscle

Explanation:

The patellar reflex is a simple reflex arc. When the knee is struck, sensory neurons (nerves) send signals to the spinal cord. Then, motor neurons (nerves) carry signals from the spinal cord back to the muscle to cause a response.

Answer:

D. Knee strike → nerve → spinal cord → nerve → muscle
