They are call synapses, there are two types chemical and electrical.
The microscopic cells with tiny connecting branches that send messages to the brain are called neurons. Neurons transmit signals through electrical impulses and communicate with each other via synapses, where neurotransmitters are released. Their intricate branching structure, known as dendrites, allows them to receive and integrate information from other neurons. This complex network is essential for processing and relaying information throughout the nervous system.
this is not 100% your answer but i know that it has many branches sticking out from the main part. to send it they send elctronic signals to your brain telling your brain something. it doesnt take long because since it has so many branches it can take a shortcut to go to the nearest place
Im not sure your brain sends your brain messages. correct me if im wrong people.

Interneurons send messages from the spinal cord to the brain.
retina is connected to the nerve and the nerve sends the messages or images to the brain and the brain processes the images
Your brain stem.
the brain stem also sorts though the millions of messages that the brain and the rest of the body sent back and forth.
The brain is like the central control system of the body. The brain sends messages to and receives messages from other organs and systems.

The brain does not receive 100 million messages per second. While the brain can process large amounts of information quickly, a specific number like 100 million messages per second is an oversimplification and not an accurate representation of how the brain functions.
as big as the microscopic part of your nail
