Intermedia ganglia (g. intermedia) are neural ganglia that are located between the cephalic and dorsal ganglia in the nervous system of vertebrates, including humans. They are part of the peripheral nervous system and perform important functions in the regulation of movement and sensation.
The intermediate ganglia are bean-shaped structures and are located along the path of the peripheral nerves. They consist of clusters of neurons that are connected to each other and to other neurons through dendrites and axons. These ganglia play an important role in transmitting information about movement and sensation from the peripheral nerves to the central nervous system and vice versa.
An important function of the intermediate ganglia is the reflex regulation of movements. When we respond to external stimuli, such as when we hit a sharp object, information about that stimulus is transmitted through the peripheral nerves to the intermedius ganglia, which respond to it by transmitting signals to the brain and causing a reflex response, such as withdrawing the arm.
Intermediate ganglia also play an important role in the regulation of sensitivity. They receive information about tactile, pain and other types of sensitivity from peripheral nerves and transmit it to the brain for processing. It allows us to sense and respond to external stimuli.
In conclusion, the intermedius ganglia are an important part of the peripheral nervous system and perform important functions in the regulation of movement and sensation. They play a key role in transmitting stimulus information from the peripheral nerves to the central nervous system and back and help us respond to our environment.
