What happens in the nervous system?
The nervous system controls and coordinates all body functions by sending and receiving electrical signals through neurons. It is divided into the central nervous system (brain and spinal cord) and the peripheral nervous system (nerves outside the brain and spinal cord). The nervous system allows for sensory perception, voluntary movement, and involuntary processes like heart rate and digestion.
How does the human brain relate to the heart?
The human brain and heart are connected through the autonomic nervous system, which regulates involuntary functions like heart rate and blood pressure. The brain sends signals to the heart via the autonomic nervous system to control its function. Additionally, emotions and stress can impact both the brain and heart, highlighting their interconnectedness.
How do i draw a diagram of what happens in the nervous and hormonal systems when somedody jumps while watching a scary movie?
When somebody jumps while watching a scary movie, their eyes and ears perceive the frightening stimulus, sending signals to the brain through sensory neurons in the nervous system. This activates the brain's fight-or-flight response, triggering the release of adrenaline and other stress hormones from glands such as the adrenal medulla. These hormones increase heart rate, blood pressure, and alertness, preparing the body to respond to the perceived threat.
How would a nerve carrying impulses from your brain to your eyelids be different to one carrying impulses to your heart?
The nerve carrying impulses from your brain to your eyelids would be a cranial nerve, such as the oculomotor nerve (responsible for eyelid movement), while the nerve carrying impulses to your heart would be part of the autonomic nervous system, such as the vagus nerve (regulating heart rate). Additionally, the nerve to the heart would primarily involve motor signals, while the nerve to the eyelids would involve sensory and motor signals for eyelid function.
Difference between a stroke and a heart attack?
Heart attack means you have one of the blood vessels choked in your heart. This gives rise to some of the part of heart dead. In stroke you usually have the blood supply of the brain affected. That gives rise to paralysis of some part of your body, usually.
Which brain region provides the signals that control the beating of the heart?
Brain stem
What controls the other between the heart and brain?
The heart and brain are interconnected through the autonomic nervous system and various biochemical signals. While the brain regulates heart function through neural pathways and hormones, the heart can also influence brain activity by sending signals that affect mood and cognition. This bidirectional communication ensures that both organs adapt to the body's needs, such as during stress or physical activity. Ultimately, they work in tandem rather than one controlling the other.
What is the function of the group of cells in the heart called pacemaker?
sending out signals to make the heart muscles contract.
What is the function of the group of cells in the heart called the pacemaker?
sending out signals to make the heart muscles contract.
While you are alive does your brain ever stop sending eletricity to your heart?
The brain does not send the electricity to the heart. The heart is myogenic which means it can contract and relax without any stimulus from the brain.
Is emotions rise from heart?
Emotions comes from your brain. It sends signals to you, and then you know what your feeling.
Where do the experience of pain take place?
The experience of pain takes place in the brain. Signals of pain are transmitted from nerve endings in the body to the brain, which processes and interprets these signals as pain.
When your alive does your brain ever stop sending electricity to your heart?
no, because your heart is specially designed to use electrical energy
How long can a person live if your brain is dead from strokes but you are still breathing and your heart is still beating?
If your brain is dead you are dead. Because that is the thing sending all the signals for your body to still function. Agreeing to the above statement, you CAN live if you have a working brain stem, however you would be a vegetable state and that is never any fun.

Can a baby survive with no brian activity?
