What else can I help you with?
What are the two channels which relay the messages to and from the brain and to the body parts that will do the action?
These "channels " are actually nerves termed as Afferent and Efferent nerves usually called motor and sensory nerves.
How does the brain send messages to the body systems?
The brain sends messages to the body systems through the nervous system. Nerve cells called neurons transmit electrical signals throughout the body, allowing for communication between the brain and different parts of the body. These signals help control movement, sensation, and various bodily functions.
What do sensory neurons carry impulses from the CNS?
The sensory (or afferent) neuron carries messages to the brain and then the motor (or efferent) neuron carries the reaction message from the brain to the gland or muscle being effected in response. :)
What carries messages to and from the brain?
The nervous system carries messages to and from the brain through a network of neurons. Sensory neurons carry information from the body to the brain, while motor neurons carry signals from the brain to the body to control movement and other functions.
What transmits messages from sense organs and the environment?
The nervous system transmits messages from sense organs and the environment to the brain through electrical and chemical signals. Sensory neurons are responsible for detecting stimuli and relaying information to the brain for processing and response.
What is intermixed neuron?
a neuron which recieve both messages from afferent and efferent neuron...
What neurons receive messages about what is happening inside and outside the body?
efferent and afferent neurons
Neurons that collect messages from sense organs and carry those to the spinal cord or the brain are called?
afferent nerves

DoesAfferent fibers carry messages to the muscles true or false?
False. Afferent fibers carry sensory information from the peripheral nerves to the central nervous system, such as information about touch, pain, temperature, etc. Efferent fibers, on the other hand, carry signals from the central nervous system to the muscles to initiate movement.
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.
What are afferent and efferent neurons and inter neurons?
These neurons are classified by the direction in which they send their messages. Afferent neurons are typically sensory neurons--neurons which send information to the brain and spine. They send information about the body and immediate environment. Efferent neurons are typically motor neurons, sending information from the brain and spine to the rest of the body. They allow the main control system a way to act on the body. Another way to distinguish these two is to think of afferent nerves as 'approaching' the brain (A) and efferent nerves as 'exiting' the brain (E). Interneurons are relay neurons and their signals, connecting efferent and afferent neurons in network. They can link up the same types or different types of neurons, meaning connecting sensory neurons together, motor neurons together, or the different types together. The simplest example of these three types working in unison is a reflex arc (which is what is activated when you hurt yourself, like stepping on a pin or burning your hand). The sensory/afferent neuron detects pain and signals the interneuron. Simultaneously, the interneuron sends a signal to your efferent/motor neurons to retract your hand/leg/whatever, while also sending a message to the brain. This is why you pull back before you feel pain :).

CAN reflex action controlled by spinal cord?
Simple reflexes are controlled by the spinal cord. The message travels from the sense receptors near the skin through the afferent nerve fibers to the spinal cord. In the spinal cord, the messages are relayed through association neurons to the efferent nerve fibers, which carry them to the muscle cells that cause the reflex movement.
How are olfactory neurons classified structurally?
Neurons are classified by the direction they move.
What cell transmits and receive nervous-system signals?
The dendrites collect information from other cells (afferent) or send information to other cells (efferent). The afferent dentrites are stimulated by chmicals from sensory cells. The efferent dentrites send chemical signals to other cells.
What do sensory neurons carry impulses from the CNS?
The sensory (or afferent) neuron carries messages to the brain and then the motor (or efferent) neuron carries the reaction message from the brain to the gland or muscle being effected in response. :)
