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 neurons that carry impulse to the brain and spinal cord called?
These are called efferent neurons. The one that carry impulses away are afferent. Afferent (A) are away (A).
What is the function of spinal nerves- afferent?
They carry nerve impulses from your sensory organs, like your eyes, to your brain, or your central nervous system (CNS). When your eyes see something shiny on the ground, your afferent nerves tell your brain what your eyes see. In contrast, efferent nerves carry nerve impulses from your brain to parts of your body. So, when you see something shiny on the ground, your brain tells you to pick it up and look at it. Efferent = "Exiting", the nerves impulses are exiting your brain. Afferent = the opposite
What are the functions of afferent and efferent nerves?
Afferent nerves are the one that carry the information from periphery to central nervous system for further processinng. While efferent nerves carry the processed information from central nervous system towards the periphery for action.
What is an afferent neuron?
Afferent neurons are those that transmit signals from sensory transducers to the central nervous system (i.e., the spinal cord and the brain). The complementary group of neurons are the efferent neurons that transmit signals from the central nervous system to effectors, that generate a response to the environmental input.
What is the bundle of nerve fibers that send messages to the brain which interprets them?
The bundle of nerve fibers that send messages to the brain for interpretation is called the sensory pathway. These pathways carry sensory information from the peripheral nervous system to the brain where it is processed and interpreted.
Whiat nerve the afferent or efferent instructs your brain to avoid touching something hot?
afferent.
What neuron connects an afferent neuron to an efferent neuron?
The interneuron acts as a connector between afferent and efferent neurons in the central nervous system. It integrates and processes incoming sensory information before transmitting signals to the efferent neuron to produce a response.
Does the efferent system sends information from the brain to spinal cord throughout the body?
You are correct; efferent neurons carry impulses from your brain to/and spinal cord throughout the body. Efferent nerves, otherwise known as motor or effector neurons, carry nerve impulses away from the central nervous system to effectors (such as muscles or glands and also the ciliated cells of the inner ear).The term 'efferent' can also be used in more localized locations (though still in the nervous system). For example, a neuron's efferent synapse provides input to another neuron, and not vice-versa. Vice-versa would be afferent. (see below)The opposite of efferent neurons are afferent, which are neurons that carry impulses from the body back to the brain. An easy mnemonic: Efferent connections Exit. Afferent connections Arrive.Hope this helps!
How does the brain help the nervous system?
The brain is the most important and central organ of the entire nervous system. It receives sensory input (afferent feedback) from the rest of the nervous system, processes information, and produces efferent signals and responses to the rest of the nervous system. Analogous to a computer system, the brain would be the central processing unit.
DIvision of the nervous system brings sensory information to the central nervous system?
The afferent neurones or Sensory neurones. Further divided to 2 subtypes, the visceral (from inner organs) and somatic (from skin). There is also the cranial nerves which provide information to the CNS.
Why are some nerves called afferent nerves and others are called efferent nerves- how do they differ in function?
Afferent nerves are those that send impulses from the PNS to the CNS. Efferent nerves send impulses from the CNS to the PNS. So the first goes toward the Central Nervous System and the second goes away from it.
