Does the SA node controlled by the brain require signals from the autonomic nervous system to send the impulses for the cardiac muscle to contract?
No. The nodes are automatic. They start the pulses by themselves. This is called an automatic pacemaker. They have no external nerve or hormonal control.
What are the main parts of the lower brain?
The different parts of the brain are: The frontal lobe, temporal lobe, occipital lobe, parietal lobe, hypothalamus, cerebrum, brain stem ,and cerebellum.The nervous system is your body's decision and communication center. The central nervous system (CNS) is made of the brain and the spinal cord and the peripheral nervous system (PNS) is made of nerves
How does Ekwefi react?
An action happens. Her organs observe and send neural impulses to her brain. Her brain processes what happens, lighting up neural pathways. These chemicals and impulses cause her brain to make decisions.
What is cerebral ganglion in earthworms?
The Ganglia is a part of the nervous systemThe Ganglia is a mass of nerve tissue existing outside the central nervous system.To make a long story short it's a brain.
What is the difference between the heart and the brain?
The heart is the organ in your chest that blood is pumped in and out of, and the brain is the organ in your head that controls everything you do (center of the nervous system)
What do electrical impulses of the brain cause?
Electrical impulses of the brain are the nervous impulses that the nervous system uses to control body functions. These impulses may be relayed within the brain, or may be carried to the peripheral nervous system.
What are the 2 divisions of the peripheral nervous system?
The sensory division of the peripheral nervous system transmits impulses from sense organs to the central nervous system. The motor division transmits impulses from the central nervous system to the muscles or glands.
The brain and spinal cord are in what divisions of the nervous system?
Central....
What are the 2 divisions of the nervous system?
Central nervous system: brain and spinal cord Peripheral nervous system: everything else
What is the difference between afferent and efferent pathways?
The major difference is the direction of travel for nerve impulses. In the afferent nervous system, the impulses are traveling away from the brain - these tend to be motor impulses. In the efferent nervous system, the impulses are traveling towards the brain - these tend to be sensory impulses.
What part of the nervous system does sensory neuron carry impulses?
brain or spinal cord
Two divisions of central nervous system?
The brain & the spinal cord
What structures are found in the peripheeal nervous system?
peripheral nervous system consist of nerves conveying impulses from brain to sense receptor and from sense receptor to brain.
What are the two division of the nervous system?
The 2 divisions of the nervous system are the central nervous system and the peripheral nervous system. Both systems have the main function of allowing communication from the brain to limbs and organs and back to the brain.
What does your spinal cord have to do with your nervous system?
It is what carries the nerve impulses between your body and the brain.
What part does an insect have its nervous system?
An insect has a brain as part of its nervous system. The brain receives and interprets sensory impulses from all ganglia on the insect's body.
What are the divisions of nervous system?
The nervous system is initially divided into the central nervous system (CNS) (brain and spinal cord) and the peripheral nervous system (PNS) (pretty much all nerves and related structures that do not reside in the brain or spinal cord). The PNS is then divided into two two divisions known as the somatic division (voluntary) and the autonomic division (involuntary). The autonomic nervous system is then once more divided into the sympathetic and parasympathetic divisions.
