The primary function of the nervous system is to transmit signals between different parts of the body, allowing for coordination, communication, and response to stimuli. 2. Why does the cerebral cortex contain so many folds? To increase its surface area, enabling a greater number of neurons and connections, which enhances cognitive abilities such as processing and integration of information. 3. What is a nerve impulse? A nerve impulse is a rapid electrochemical signal transmitted along the length of a neuron, facilitating communication between neurons and allowing for the transmission of information within the nervous system. 4. What are Schwann cells and what do they form? Schwann cells are a type of glial cell in the peripheral nervous system that form the myelin sheath, which insulates and enhances the conduction speed of nerve impulses along axons. 5. What is an all-or-none response? An all -or-none response refers to the principle that once a nerve impulse reaches a certain threshold, a neuron will fire at its maximum potential, regardless of the strength of the stimulus. 6. What two effects might neurotransmitters have? Lab 8 The Nervous System BIO201L Neurotransmitters can either excite or inhibit the activity of neighboring neurons, regulating the transmission of signals within the nervous system. Lab 8 The Nervous System BIO201L EXPERIMENT 1: MICROSCOPIC ANATOMY OF NERVOUS SYSTEM Introduction Questions 1. What is the major function of the neuron? The major function of a neuron is to transmit electrochemical signals, called nerve impulses, throughout the nervous system, enabling communication between different parts of the body. 2. Define depolarization. Depolarization is the process in which the membrane potential of a neuron becomes less negative, typically due to an influx of positively charged ions, leading to the generation of an action potential. 3. What determines whether a neuron is unipolar, bipolar, or multipolar? The number of processes extending from the neuron's cell body, including dendrites and axons Data and Observations 1. Label the arrows in the slide images below based on your observations from the experiment. A. Axon B. cell bodies C. myelinated axons D. myelin sheaths
