LECTURE 2 p1

• A neuron has 4 separate parts the dendrites soma axon and terminal buttons
• the main function of dendrites is to receive information from other neurons
• The cell (soma) body contains genetic information, maintains the neuron's structure, and provides energy to drive activities
• An axon is a long, slender projection of a nerve cell (neuron) that transmits electrical impulses, or action potentials, away from the cell body, typically to other neurons, muscles, or glands. 
• Terminal buttons bulbous ends of a neuron's axon that release neurotransmitters into the synapse to transmit signals to other cells. 
• Bipolar and unipolar neurons are two different types of neurons based on their structure and function.
• • Bipolar neurons have two extensions (one axon and one dendrite) emerging from opposite ends of the cell body.
• • Unipolar neurons have a single extension from the cell body that branches into two (one process functioning as an axon and the other as a dendrite).
• Multipolar neurons have multiple extensions—one axon and two or more dendrites—emerging from the cell body
• Multipolar neurons can have two types of axons long and short golgi one are longer axons and golgi 2 are shorter axons
• a neurons has 3 major functions a sensation (feeling) integration (processing) and action (movement)
• Sensory neurons carry signals from sensory receptors to the central nervous system (CNS) (brain and spinal cord). They detect external stimuli (such as touch, temperature, and pain) and internal changes (like blood pressure and muscle stretch)
• Motor neurons transmit signals from the CNS to muscles and glands to control movement and physiological responses.
• Interneurons connect sensory and motor neurons within the CNS, processing information and coordinating responses.
