6.4.1 Motor and Somatosensory Areas

    Cards (26)

    • Localisation of function in the brain refers to the idea that different brain areas are specialized for different functions
    • The somatosensory area processes sensory information from the body.
    • The motor cortex is located in the frontal lobe.
    • Damage to the motor cortex can result in impaired sensation.
      False
    • Specific brain areas are responsible for specific tasks, such as movement or sensation.
    • Match the brain area with its function:
      Motor cortex ↔️ Controls voluntary movements
      Somatosensory cortex ↔️ Processes sensory information
    • The motor cortex is located in the parietal lobe.
      False
    • The motor cortex controls voluntary movements.
    • The somatosensory cortex is located in the parietal lobe.
    • Topographical organisation in the motor cortex allows for precise control of voluntary movements.
    • Match the brain area feature with its description:
      Motor areas ↔️ Control adjacent muscle groups
      Somatosensory areas ↔️ Process sensory information
    • Arrange the following steps to describe topographical organisation in motor areas:
      1️⃣ Motor cortex is divided into regions
      2️⃣ Regions control specific muscle groups
      3️⃣ Neighbouring regions control adjacent body parts
    • The somatosensory cortex processes voluntary movements.
      False
    • The motor cortex is located in the frontal lobe.
    • What does the concept of localisation of function in the brain refer to?
      Brain areas are specialised
    • The motor cortex is located in the frontal lobe.
    • What does the motor cortex control?
      Voluntary movements
    • Each area of the motor cortex corresponds to different muscle groups.
    • The somatosensory cortex is located in the parietal lobe.
    • What does the somatosensory cortex process?
      Sensory information
    • Topographical organisation in the brain ensures that adjacent areas in the motor cortex control adjacent body parts.
    • Topographical organisation enables precise control of voluntary movements.
    • Match the brain area with its function or characteristic:
      Motor Cortex ↔️ Controls voluntary movements
      Somatosensory Cortex ↔️ Processes sensory information
      Topographical Organisation ↔️ Adjacent areas control adjacent body parts
    • Arrange the following symptoms of damage to the motor cortex in order of severity:
      1️⃣ Muscle weakness
      2️⃣ Paralysis
      3️⃣ Difficulties with coordination
    • What is a common symptom of damage to the somatosensory cortex?
      Loss of sensation
    • Damage to the somatosensory cortex can cause numbness or tingling sensations.
