The University of Arkansas defines the average all around body weight of an adult to be roughly 70 kilograms or 154 pounds (1pound is about 0.4539 kg). But that clearly cannot be 100% accurate. I myself weight in at 79 kg (175 lbs), yet I am not obese or overweight. There are factors to consider.
Nerves. Nerves are bundles of axons in the peripheral nervous system (PNS) that act as information highways to carry signals between the brain and spinal cord and the rest of the body. Each axon is wrapped in a connective tissue sheath called the endoneurium. Afferent, Efferent, and Mixed Nerves. 2  Some of the nerves in the body are specialized for carrying information in only one direction, similar to a one-way street. 3  Nerves that carry information from sensory receptors to the central nervous system only are called afferent nerves.
The somatic nervous system is part of the efferent division of the PNS and is considered to be the voluntary branch. The axons of this system are called motor neurons and are used to innervate skeletal muscle. ACh is released from the motor neurons, and stimulates skeletal muscle, causing it to contract.he peripheral nervous system (PNS) is part of the overall nervous sytem of the body. The overall nervous system consists of two sections â the central nervous system (CNS) and the peripheral nervous system (PNS). An overview of the cells of the nervous system can be found here.
