The electrical impulse bypasses the concious areas of your brain so you don't think about subconcious things, like reflex actions for example. This is to help you in dangerous situations and to help you survive.

What is fore-brain?
The forebrain is a term used to designate the area of the brain that is responsible for the brain's critical and complex thinking, judgment making, and controlling impulses.
The part of the brain that translates the impulses that the eyes receive into vision is the?
Association area of the cerebral cortex
Where do impulses to the muscles originate?
The "impulses" to skeletal muscles come primarily from alpha motor neurons in the ventral horn of the spinal cord. These neurons release acetylcholine on the muscles, which causes sodium to enter the muscle, leading to contraction. The alpha motor neurons themselves get input from several sources, such as the primary motor area in the cerebral cortex of the brain. However, even this brain area gets input from other brain areas, including sensory areas. In a certain sense, the impulses to the muscles "originate" from the environment in the form of sensory signals.
Describe breifly the nervous system?
The nervous system in the human body can best be described as a super highway. Nerve impulses reach the brain and go back to the significant area in seconds.
How do spikes and receptors interact?
It reacts in these following steps: 1) A spike (the stimulus) is touched by receptors in the skin. 2) Receptors in the skin detect the stimulus and send electrical impulses down neurones to the sensory neurone. 3) The sensory neurone will pass these electrical signals to the CNS (Central Nervous System). 4) The CNS will pass these electrical signals to the motor neurone which once connected to the brain (through nervous cells reaching the carotid area of the body), the brain will detect and understand the feeling of the spike and will send this information the receptors.
Can you see a real ghost?
No. Mostly you see something in an area where there is heavy electromagnetic surges due to the magnetic field of the Earth and the Sun's solar flares so the electrical impulses in your brain have to adjust themselves, and due to the mood you are in plus the atmosphere of the envirment, your mind will, so to say, play tricks on you.
What does your brain do when you want to wave your hand?
It sends an impulse to the hand area to move so basically it sends impulses to tell the hand what to do cause its the command center
What nerve carries the action potentials from the ganglion cells to the thalamus of the brain?
The optic nerves carry the impulses from the eyes to the visual area of the thalamus.
What fiber tracts carry signals about voluntary movement to the spinal cord?
The basal ganglion are responsible for carrying the impulses from the cerebral cortex to the cerebellum. The impulses pass through the brain stem in an area called the pons where they cross-over and switch sides of the body. This is why your left side of your brain controls the right side, and visa versa.
What are nerve blocks?
Nerve blocks involve the injection of an anesthetic into the area around a nerve that supplies a particular region of the body, preventing the nerve from carrying nerve impulses to the brain.
What nerve is carrying impulses from the eye to the thalamus?
The optic nerves carry the impulses from the eyes to the visual area of the thalamus.
How does the brain work with organ systems?
The brain regulates everything. Each area of the brain has a specific fonction. the nerves communicate messages to the brain (electric influx). the brain decrypt the information and regulates the actions the nerves and muscles have to do. Without electrical activity on the brain there is no life .
