The parasympathetic motor pathways begin in the areas?
Most parasympathetic motor pathways begin in the dorsal aspect of the medulla, in the dorsal motor nucleus of the vagus nerve. Parasympathetic motor pathways also come from the preganglionic cell bodies located in the lateral horn of the spinal cord in the sacral region (pelvic splanchnic nerves). Thus, the description cranio-sacral is often used to describe the origins of the parasympathetic innervation.
What pathways do sensory signals take from the periphery to the highest levels?
by afferent and efferent path ways
How is the afferent and efferent pathway important for sensation in your body?
Afferent pathways communicate sensory information (e.g. pain, cold) from your sensory organs to your central nervous system. Efferent pathways communicate information from your central nervous system to your effector organs (e.g. muscles and glands).
Which pathways comprise the autonomic nervous system?
two-neuron chain from CNS to effector organs. Parasympathetic and Sympathetic.
Difference between afferent and efferent in kidney?
Efferent means going away from and afferent is going toward. The afferent arteriole of the kidney carrys blood toward the glomerulus, whereas the efferent arteriole carrys blood away from the glomerulus.
Where is the neuron?
The Inter-neuron (also known as the local circuit neuron, relay neuron or the association neuron) is the neuron which connects the afferent and the efferent neurons in the neural pathways.
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 peripheral nervous system carries the sensory and motor information to and from the central nervous system?
You have thousands of nerves that are part of the PNS.Divisions of the peripheral nervous system include the afferent (sensory) division and the efferent (motor) division. The nerves coming from all the senses and the nerves going to glands and muscles are included.The efferent division is divided further into the somatic motor nervous system and thesomatic nervous system which includes all voluntary motor pathways outside the central nervous system.
What does cyloplasm do?
The cytoplasm is the site where most cellular activities occur, such as many metabolic pathways, and processes such as cell division.
Why would one of a baby's eyes be more dilated than the other?
This condition is called "Anisocoria". Anisocoria is usually the result of a defect in efferent nervous pathways controlling the pupil traveling in the oculomotor nerve (parasympathetic fibers) or the sympathetic pathways. It may be associated with Adie syndrome, Horner's syndrome ... etc.
What is the difference between afferent and efferent nerve fibers?
Afferent refers to pathways leading to the cortex (ie, sensory). Efferent are pathways leading away (ie, motor). You are *affected* by a situation, you *effect* change on someone else.
What does a bundle of neurons form?
A bundle of neurons is called a nerve. The neuron bundle, nerve, has afferent and efferent pathways, that means that it is like highways that are parallel to each other yet carry impulses, or traffic, in both directions.
