What is it capillaries do?
they are tiny blood vessels around the body that connect arteries to veins. they transport oxygen,nutrients etc around the body and collect waste products
Which neurons are foundonly within the brain and spinal cord?
Scientists have organized the cells that make up the nervous system into two broad groups: neurons, which are the primary signaling cells, and glia, which support neurons in various ways. The human brain contains around 100 billion neurons and, by most estimates, somewhere between 10 to 50 times as many glial cells. Bipolar ones are usually found outside the brain and interneurons are found within the brain.
What is between sensory neurons and motor neurons?
sensory has to do with your smell tast motor has to do with your moving around and you acttion
Where on the neurons are the dendrites located?
Around the cell body
What is the function of a neuroglia?
Neuroglia are helper cells in the nervous system. They produce products that help support and protect the neurons so they can do their work transmitting impulses, also called action potentials.
What are any tubes that carry blood called?
Blood vessels are the tubes that carry blood. The three types of blood vessels are arteries, capillaries, and veins.
Have bees got brains?
Yes, bees do have a brain. It has around 950,000 neurons compared to the more than a billion neurons in a human brain.
Why are there blood vessels around the brain?
The blood vessels around the brain help supply energy for your brain
How do you create myelenated neurons?
You don't, but glial cells, (oligodendrocytes in the CNS, and Schwann cells in the PNS), wrapped one after another around the axons of neurons with gaps between them called the nodes of Ravnier do create myelinated neurons.
What are the tiny blood vessels that wrap around the air sacs?
Capillaries . The smallest of the blood vessels: capillaries.
What is the work of blood vessels?
the blood vessels are the passageways of blood from the heart and back to it after it circulate around the body.
How many nerves in the human brain?
There are around 10 billion neurons in the brain.
