What type of cell has a long arm?
Neurons.
What electrical impulse travels outward from the cell body along what?
Typically, the electrical signal that travels from the dendrites across the cell body travels by cable conduction properties (like cable TV). Once the signal reaches the axon hillock, which is the spot where the axon branches off the cell body, the electrical signal starts traveling by action potentials (and maybe some cable conduction). The signal travels to the terminal end of the axon where it initiates a calcium influx, which in turn initiates a release of neurotransmitter to act on the next, post-synaptic neuron. The axon is the long process (arm) that extends from the first cell body to the next neuron.
What type of cell is in your brain and is shaped to send signals?
Neurons are one type of brain cell that sends and receives signals. Neurons have three parts: 1. cell body - where the nucleus is 2. axon - extends from the neuron 3. dendrites-branches that extend from the far end of the axon I like to think of it as a cell with a long arm that has branches at the end. The long arm has insulation (myelin) around it that makes it conduct signals faster than a non myelinated cell. Take two neurons whose axons extend toward each other so the dendrites are close. When the electric wave sent from the first cell reaches the dendrites at the far end, the signal, in the form of a molecule with and electric charge, moves to where the dendrite of the other neuron can catch the signal and send it on. You need at least 2 neurons to transmit a signal: one to make the signal and the other to receive it.
What is the function of the motor neuron?
Neurons come in many sizes. For example, a single sensory neuron from your fingertip has an axon that extends the length of your arm, while neurons within the brain may extend only a few millimeters. Neurons have different shapes depending on what they do. Motor neurons that control muscle contractions have a cell body on one end, a long axon in the middle and dendrites on the other end; sensory neurons have dendrites on both ends, connected by a long axon with a cell body in the middle.
What is the main type of cell found in your muscle in your arm?
adenosine triphosphate (ATP)

The muscles of the arm are composed primarily of what cell type?
Skeletal muscle cells
What type of chromosomal disorder causes sickle cell anemia?
on the short arm of chromosome 11
What is the structure of a nerve cell?
The structural unit of a nervous system is the nerve cell or neuron.The message that travels along a neuron is called an impulse.Each neuron consist of a cell body called Cyton.The cell body contains the nucleus.Several short fibre like structures extend from the cell body called Dendronswhich further divide into Dendrites.It receives message from other neurons.A single long fibre called Axon extend from the other side of the cell body which carries message from the cell body of one neuron to another.The neurons do not actually touch each other but communicate via Synapse where the axon terminal of one neuron impringes the dendrites of another neuron. Synapse is a junction for communication between neurons.
The muscles of your arm are primarily composed of what cell type?
The arm muscles are made up of muscle fibers or skeletal muscles. The shape of the body is held together with the help of these muscles.
What is the source of chemical enegry used to power a muscle cell in your arm?
ATP is the source of chemical energy used to power a muscle cell in your arm.
What is the difference between arm and hand?
An arm is what you used to type the question. The hand is what I used to type this answer.
When was The Long Arm of the Law created?
The Long Arm of the Law was created in 1980.
