      Cranial and spinal nerves

    • C.

      Pyramidal and extrapyramidal systems

    Correct Answer
    B. Cranial and spinal nerves
    Explanation
    The lower motor neuron system is made up of cranial and spinal nerves. These nerves are responsible for transmitting signals from the central nervous system to the muscles, allowing for voluntary movement. The cranial nerves originate in the brain and control the muscles of the head and neck, while the spinal nerves originate in the spinal cord and control the muscles of the rest of the body. This system is essential for motor function and coordination.

    The indirect activation pathway

    • A.

      Mediates contolled voluntary movements

    • B.

      Mediates subconsious automatic muscle activities (posture, muscle tone, etc)

    Correct Answer
    B. Mediates subconsious automatic muscle activities (posture, muscle tone, etc)
    Explanation
    The indirect activation pathway is responsible for mediating subconscious automatic muscle activities such as maintaining posture and muscle tone. This pathway operates without conscious control and helps to regulate the body's movements and maintain stability. It is distinct from the direct activation pathway, which is involved in controlled voluntary movements.

    The indirect activation pathway is a

    • A.

      Lower motor neuron system

    • B.

      Upper motor neuron system

    Correct Answer
    B. Upper motor neuron system
    Explanation
    The given correct answer is "upper motor neuron system." The upper motor neuron system refers to the pathway responsible for conveying signals from the brain to the lower motor neurons, which in turn control muscle movement. This system consists of neurons located in the cerebral cortex, brainstem, and spinal cord. It plays a crucial role in initiating and coordinating voluntary movements.

    The extrapyramidal tracts is made up of

    • A.

      Corticobulbar and corticospinal tracts

    • B.

      Corticorubral,corticoreticular, rubrospinal, reticulospinal, and vestibulospinal tracts

    Correct Answer
    B. Corticorubral,corticoreticular, rubrospinal, reticulospinal, and vestibulospinal tracts
    Explanation
    The extrapyramidal tracts are a collection of neural pathways that are involved in motor control and coordination. These tracts are responsible for regulating involuntary movements, posture, and muscle tone. The corticorubral tract connects the cerebral cortex to the red nucleus in the midbrain, while the corticoreticular tract connects the cortex to the reticular formation in the brainstem. The rubrospinal tract originates in the red nucleus and controls voluntary movements. The reticulospinal tract originates in the reticular formation and modulates muscle tone and reflexes. The vestibulospinal tract originates in the vestibular nuclei and helps maintain balance and posture.

    The control circuitry system is all about the

    • A.

      Pyramidal system - corticospinal and corticobulbar tracts

    • B.

      The extrapyramidal system - basal ganglia

    Correct Answer
    B. The extrapyramidal system - basal ganglia
    Explanation
    The control circuitry system consists of two main components: the pyramidal system and the extrapyramidal system. The pyramidal system includes the corticospinal and corticobulbar tracts, which are responsible for voluntary movements and motor control. On the other hand, the extrapyramidal system involves the basal ganglia, which plays a crucial role in regulating movement, posture, and muscle tone. Therefore, the correct answer is the extrapyramidal system - basal ganglia.
