2.3.1 Structure and Function of the Nervous System

• The spinal cord transmits signals between the brain and the body.

  True
• Arrange the following steps in the nervous system's response to stimuli:

  1️⃣ Sensory Input

  2️⃣ Integration

  3️⃣ Motor Output
• What is the integration phase of the nervous system's response to stimuli?

  Processing sensory information
• The brain and spinal cord work together in the CNS to process information.

  True
• What are the three basic functions of the nervous system?

  Sensory input, integration, motor output
• Match the brain division with its key features:

  Brain ↔️ Processes sensory information

  Spinal Cord ↔️ Transmits signals, controls reflexes
• The spinal cord is the primary pathway for communication between the brain and the body.


  True
• The nervous system is divided into the CNS and the PNS.
• The brainstem regulates unconscious bodily functions.


  True
• Order the divisions of the brain from top to bottom.

  1️⃣ Cerebrum

  2️⃣ Cerebellum

  3️⃣ Brainstem
• What is one key function of the spinal cord?

  Transmitting signals
• What do nerves in the PNS transmit?

  Sensory information
• The somatic nervous system is responsible for voluntary movement and conscious sensations
• Order the responses to a stressful situation according to the sympathetic and parasympathetic nervous systems.

  1️⃣ Sympathetic nervous system prepares the body for action

  2️⃣ Heart rate and breathing increase

  3️⃣ Parasympathetic nervous system restores the body to a resting state

  4️⃣ Heart rate and breathing slow down
• What are the three main functions of the nervous system?

  Sensory input, integration, motor output
• The main parts of the central nervous system (CNS) are the brain and the spinal
• Match the nervous system division with its function:

  Somatic Nervous System ↔️ Controls voluntary movements

  Autonomic Nervous System ↔️ Regulates involuntary actions
• Sensory input in the nervous system involves gathering information through sensory receptors
• Match the nervous system division with its key components:

  Central Nervous System (CNS) ↔️ Brain and Spinal Cord

  Peripheral Nervous System (PNS) ↔️ Nerves and Sensory Receptors
• What is the main function of the spinal cord?

  Transmit signals, control reflexes
• The PNS transmits signals between the CNS and the rest of the body.


  True
• The cerebrum, cerebellum, and brainstem are key divisions of the brain.
• The spinal cord mediates rapid, involuntary responses to stimuli called reflexes.

  True
• The Central Nervous System (CNS) consists of the brain and the spinal
• What are the two main parts of the CNS?

  Brain and spinal cord
• The spinal cord extends from the base of the brain down the back
• The Peripheral Nervous System (PNS) consists of nerves and sensory receptors
• How does the PNS allow the body to respond to external stimuli?

  By transmitting signals
• What type of neurons connect the CNS to skeletal muscles in the somatic nervous system?

  Motor neurons
• The sympathetic and parasympathetic nervous systems work together to maintain homeostasis.


  True
• What are the key components of the Central Nervous System (CNS)?

  Brain and Spinal Cord
• What are the three main functions of the nervous system?

  Sensory input, integration, motor output
• The brain processes information, while the spinal cord transmits signals between the brain and the body.


  True
• The spinal cord transmits signals between the brain and the body.

  True
• Match the nervous system branch with its key feature:

  Somatic Nervous System ↔️ Controls voluntary movements

  Autonomic Nervous System ↔️ Manages involuntary bodily functions
• What is the nervous system defined as?

  Complex network for bodily control
• What does the peripheral nervous system (PNS) transmit signals between?

  CNS and rest of body
• The nervous system coordinates sensory input, integration, and motor output.

  True
• What does motor output involve in the nervous system?

  Signals to muscles and glands
• The brain is divided into the cerebrum, cerebellum, and brainstem
