Neuroscience Practice Sheet
Introduction
Neuroscience is the scientific study of the nervous system, including the brain, spinal cord, and peripheral nerves. It is a complex and fascinating field of study, and understanding it can help us understand how the brain works, how we think and feel, and how the body functions.
Basic Concepts
- What is the nervous system?
The nervous system is a complex network of cells and tissues that send signals throughout the body. It is composed of the brain, spinal cord, and peripheral nerves. The nervous system is responsible for controlling and coordinating the body's activities.
- What is the difference between the central nervous system and the peripheral nervous system?
The central nervous system (CNS) is composed of the brain and spinal cord. It is responsible for processing and integrating information from the body and the environment. The peripheral nervous system (PNS) is made up of the nerves that connect the CNS to the rest of the body. The PNS is responsible for transmitting signals from the CNS to the body and vice versa.
- What are neurons?
Neurons are specialized cells that transmit electrical signals throughout the body. They are the basic units of the nervous system and are responsible for communication between different parts of the body.
- What is a synapse?
A synapse is a specialized junction between two neurons. It is responsible for transmitting electrical signals from one neuron to another.
- What is a neurotransmitter?
A neurotransmitter is a chemical messenger released by a neuron at a synapse. It is responsible for transmitting signals from one neuron to another.
Practice Problems
- What is the function of the peripheral nervous system?
The peripheral nervous system is responsible for transmitting signals from the central nervous system to the rest of the body and vice versa. It is composed of nerves that connect the brain and spinal cord to the rest of the body.
- What is the role of neurons in the nervous system?
Neurons are the basic units of the nervous system. They are specialized cells that transmit electrical signals throughout the body. They are responsible for communication between different parts of the body.
