Hello. This question is incomplete. You forgot to attach the image that completes the question.

The image is attached below:

Answer:

A- Sensory Neuron

B- Spinal cord

C- Effector neuron

D - Brain

Explanation:

  1. Sensory neuron: Its main function is to allow the reception of stimuli that are transformed into nervous impulses and electrical signals, capable of realizing sensations, such as a peliscão, for example. These impulses are transmitted to the spinal cord.
  2. Spinal cord: The main function is to support the body in an upright and vertical position. It also has the function of transmitting electrical signals and nerve impulses between some parts of the body and the brain.
  3. Effector neuron: Its main function is to receive muscle stimuli capable of creating muscle contractions. These neurons are located in the spinal cord.
  4. Brain: the processing center receives all the stimuli sent by the bone marrow. Its main function, in this case, is to produce bodily responses to the stimuli it has received, producing muscle movement.

Why do Plants cells have cell walls and Animal cells do not?​

Plants need a rigid structure. Animal cells have flexible cell membranes. So animal cells can have a variety of shapes, but plant cells can not, they have to take the shape of their cell walls. Both plant and animal cells are eukaryotic, so they contain membrane-bound organelles like the nucleus and mitochondria.
