What are the nonspecific ascending pathways?

The nonspecific ascending pathways are neural pathways that carry sensory information related to pain, temperature, and crude touch. These pathways are not as precise in their localization of sensory input compared to specific ascending pathways. Examples include the spinothalamic tract and spinoreticular tract.


What are sensory neural pathways?

The sensory neural pathways set the brain's ability to interpret signals that control intellectual, emotional, psychological and physical responses to stimuli. The sensory systems ie. vision, hearing, touch, taste, smell and proprioceptor motion bring sensory signals to the brain and then interpret those signals. During development there is a critical period for sensory neural circuits. To form what is known as synapses (the connection between neurons that helps to carry these signals from neuron to neuron ), stimuli is needed. When this stimulation is not available in the critical period and deficits occur in the region of the cortex responsible, it can not be corrected at a later stage.


What brain structure directs sensory and motor neuron pathways passing between spinal cord and cerebral cortex?

The thalamus is the brain structure that directs sensory and motor neuron pathways passing between the spinal cord and cerebral cortex. It acts as a relay station for sensory information to reach the cortex for processing and plays a key role in regulating motor functions.


True or false Most of the ascending and descending pathways to and from the brain cross over from one sid of the body to the other?

True. Most ascending pathways carry sensory information to the brain, and most descending pathways carry motor commands from the brain to the body, crossing over from one side of the body to the other at some point. This crossover is known as decussation.


What is the role of spinal nerves in the transmission of sensory and motor signals throughout the body?

Spinal nerves play a crucial role in transmitting sensory information from the body to the brain and sending motor signals from the brain to the muscles. They act as communication pathways that allow the brain to receive information about sensations and control movements throughout the body.

What are the four Parts of the Sensory Pathway?

Sensory pathways function to provide us with information about our environment. The four parts of the sensory pathway are receptors, sensory neurons, sensory tracts, and sensory areas of the brain.


What does a sensory system include?

A sensory system includes the sensory receptors, neural pathways, and the parts of the brain which are involved in sensory perception. The senses act as the transducers from the physical world to the mind where the information gathered by the senses is interpreted.

What is the intensity of a sensation is determined by what?

The intensity of a sensation is determined by the magnitude of the stimulus that evokes it. This can be influenced by factors such as the strength or amount of the stimulus, the sensory receptors involved, and the sensory pathways that transmit the signal to the brain.


Impulses from the sense organs travel to the brain along what?

Impulses from the sense organs travel to the brain along nerve fibers known as sensory neurons. These neurons carry the signals to the brain, where they are processed and interpreted to create our perceptions and sensations.


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.


When you touch something how long does it take to tell your brain?

It takes approximately 0.07-0.25 seconds for signals of touch to travel from your skin to your brain. This information is transmitted through nerve pathways that carry the sensory signals to the brain for interpretation.


How are messages from the femoral nerve sent to the brain?

Messages from the femoral nerve are sent to the brain through a series of electrical impulses. These impulses travel along the nerve fibers of the femoral nerve until they reach the spinal cord, where they are then transmitted up to the brain via the spinal cord's sensory pathways. Once in the brain, the messages are interpreted and processed to produce a response or sensation.
