Bundles of fibres running between the Central Nervous System (CNS) and all the tissues of the body are called Nerves. These nerves make up the Peripheral Nervous System (PNS). The correct name for the fibres in these bundles is Axons which are the long part of neuron cells carrying the signal from the cell body to the Target Tissue.
Those would be nerves, which make up the nervous system.
Unmyelinated nerve fibers are slower than myelinated nerve fibers. The fibers covered by myelin are much faster.
Neurons transmit messages to and from the brain.
sarcoplasmic reticulum
Bundles of neuron processes are called tracts in the cns and nerves in the pns
your spine and skeletal system sends messages that you are in pain when your bones break. your eyes send messages about what you are seeing your fingers, arms, and every other part of your body responds to what you are touching and also sends messages to your brain to stimulate responses in whether it is a good or bad pain.

Spinal cord
the bottom 2 do not connect to anything, the rest join at the sternum or breastbone
Peripheral nervous system
sarcoplasmic reticulum
Yes. They do. Otherwise your heart couldn't pump blood to said body if they weren't connected. Fyi. Veins carry blood towards the heart from the body, and arteries carry blood from the heart to the rest of the body.
vesicles because the rest are all part of prophase.

a body at rest may have speed
A body at rest and a body in motion have completely different velocities.Magnitude of velocity:At rest . . . zeroMoving . . . not zeroDirection of velocity:At rest . . . no directionMoving . . . some direction
The heart is the organ responsible for pumping blood to the rest of the body.
