Cross-sectional diagram of a spider's trichobothrium, showing a long tactile hair (seta) anchored in a socket. Labeled parts include the bothrium, membrane, helmet, nerve processes, and cylinder.

Diagram showing the knee jerk reflex: a reflex hammer strikes the patellar tendon below the knee, activating a stretch receptor in the quadriceps muscle. This sends a signal through a sensory neuron to the spinal cord, where it connects to a motor neuron. The motor neuron then signals the muscle to contract, causing the lower leg to kick forward. The diagram also illustrates the pathway of sensory and motor neurons and their connection in the spinal cord.
