consists of the central nervous system (CNS)‚ made up of the brain and the spinal cord‚ and the peripheral nervous system (PNS)‚ the neurons that link the CNS to our skin‚ muscles‚ and glands. And we will see that our behavior is also influenced in large part by the endocrine system‚ the chemical regulator of the body that consists of glands that secrete hormones. A neuron is a cell in the nervous system whose function it is to receive and transmit information soma‚ which contains the nucleus of the

Somatic lower motor neuron is in ventral horn of gray matter and neurotransmitter at skeletal muscle is Ach. Visceral motor comes from cranial nerves or intermediolateral gray horn‚ involves 2 neurons and the neurotransmitter is either Ach or NE at either cardiac muscle‚ smooth muscle or glands.

Introduction A Brain-Computer Interface (BCI) provides a new communication channel between the human brain and the computer.The 100 billion neurons communicate via minute electrochemical impulses‚ shifting patterns sparking like fireflies on a summer evening‚ that produce movement‚ expression‚ words. Mental activity leads to changes of electrophysiological signals. The BCI system detects

Neuron (from the brain or spinal cord) will passed action potential through axon of motor neuron to an axon terminal. Sodium ion (Na+) and calcium ion (K+) are higher concentration outside than from the inside of the muscle and neuron. Na+ and K+ want to go inside but blocked by these channels (voltage gated

The cerebral cortex is responsible for higher functions of the nervous system‚ including voluntary muscle activity and learning‚ language‚ and memory. It is composed of neurons and axons.

Chapter 2- Darwin was the first to suggest how evolutionoccurs. Humans belong to the primate family known as hominins. Characteristics that evolved to perform one function but were co-opted to perform another function are called exaptations. Each group of three consecutive nucleotide bases along the strand of messenger RNA is called a codon‚ which instructs the ribosome to add amino acids to the protein being constructed. Subsequent to the nature-nuture issue‚ a second line of thought surrounding
