Jenna's pencil fell off of her desk and she quickly reached down to catch it before it hit the ground. In the process, the (1)_____ system first recognized the falling pencil. It sent signals to the (2)______ system, which then moved the components of the(3) _____ system in order to catch the pencil.

Options:

(1) 1. Nervous 2. Muscular 3. Skeletal

(2) 1. Nervous 2. Muscular 3. Skeletal

(3) 1. Skeletal 2. Digestive 3. Nervous

<h3>The answer is:</h3>

Jenna's pencil fell off of her desk and she quickly reached down to catch it before it hit the ground. In the process, the (1) <u>Nervous</u> system first recognized the falling pencil. It sent signals to the (2) <u>Muscular</u> system, which then moved the components of the(3)<u> Skeletal</u> system in order to catch the pencil.

Explanation:

The nervous system receives the signal that the pencil is falling. In other words, Jenna sees or feels that the pencil falls, so the senses send a signal to the nervous system to produce a response. We call this a stimuli. Once that the nervous system receives and processes the stimuli, it elaborates an answer. The answer is to send a signal to a group of muscles that will move certain bones to make the movement that will catch the pencil. The muscles are from the muscular system, and they are attached to the bones, which are part of the skeletal system. When the muscles contract, they move the bones and make the movement possible.
