Conscious control of the triceps surae is slower than the reflex response to the Achilles tendon tap because conscious control involves the brain sending input directly to the triceps surae and bypassing the spinal cord motoneurons involved in the reflex control.

All of the following are involved in graded contractions of an entire muscle except

of the response reflects the time taken for the muscle AP to travel to the sarcoplasmic reticulum

Passive force increases with muscle length.

The patellar tendon reflex (eg knee jerk) is an example of a (1) __________ stretch reflex, whereas the flexion reflex is an example of a (2)__________ stretch reflex

Action potentials are able to sum to produce stronger action potentials which in turn induce stronger muscle contractions

of the response reflects the time taken for the Ca++ released from the sarcoplasmic reticulum to bind to Tropomyosin.
