El sistema nervioso: la red que controla tu cuerpo

The video tutorial explains the nervous system's role in controlling body processes, from simple reflexes to complex thoughts. It describes how the nervous system detects and responds to stimuli, both external and internal. The central nervous system, comprising the brain and spinal cord, and the peripheral nervous system, which includes the autonomic and somatic systems, are detailed. The tutorial also covers how sensory neurons transmit impulses to the spinal cord, leading to muscle contractions, and how complex neural pathways in the brain produce thoughts, emotions, and behaviors.

What is the primary function of the nervous system?

• To digest food

• To regulate blood sugar levels

• To detect and respond to stimuli

• To produce hormones

Which components make up the central nervous system?

• Muscles and bones

• Brain and spinal cord

• Heart and lungs

• Liver and kidneys

What is the role of the peripheral nervous system?

• To filter waste from the blood

• To store energy

• To produce red blood cells

• To connect the central nervous system to the rest of the body

Which system controls involuntary functions like heart rate and digestion?

• Somatic system

• Autonomic system

• Central nervous system

• Endocrine system

How do sensory neurons and motor neurons interact?

• Sensory neurons transmit signals to muscles directly

• Motor neurons carry impulses to the brain

• Sensory neurons carry impulses to the spinal cord, which then transmits signals through motor neurons to muscles

• Motor neurons detect external stimuli
