  • 2. 

    The Primary Visual Cortex receives info from:

    • Lateral geniculate nucleus

    • Lateral lemniscus

    • Medial lemniscus

    • Medial geniculate nucleus

    Correct Answer
    A. Lateral geniculate nucleus
    Explanation
    The correct answer is the lateral geniculate nucleus. The primary visual cortex is responsible for processing visual information received from the eyes. The lateral geniculate nucleus is a relay center in the thalamus that receives visual information from the optic tract and sends it to the primary visual cortex. The lateral lemniscus and medial lemniscus are involved in auditory processing, while the medial geniculate nucleus is involved in auditory and somatosensory processing. Therefore, the lateral geniculate nucleus is the most appropriate choice for receiving visual information in the primary visual cortex.

    Select the incorrect match.

    • Primary Motor Cortex; Brodmann 4

    • Primary Somatosensory Cortex; Brodmaan 3,1,2

    • Primary Auditory Cortex; Brodmann 41

    • Primary Visual Cortex; Brodmann 18

    Correct Answer
    A. Primary Visual Cortex; Brodmann 18
    Explanation
    Primary visual cortex is located in Brodmann area 17

  • 4. 

    The Primary Auditory Cortex receives info from:

    • Sensory thalamus

    • Medial geniculate nucleus

    • Lateral geniculate nucleus

    Correct Answer
    A. Medial geniculate nucleus
    Explanation
    The Primary Auditory Cortex receives information from the medial geniculate nucleus. The medial geniculate nucleus is a part of the thalamus, which acts as a relay station for sensory information. It specifically processes auditory information and sends it to the Primary Auditory Cortex, where further processing and interpretation of sound occurs. The lateral geniculate nucleus, on the other hand, is involved in processing visual information and does not directly contribute to auditory processing.

    The Primar Visual Cortex sends info to:

    • Superior colliculus

    • Basal ganglia

    • Hypothalamus

    • Limbic system

    Correct Answer
    A. Superior colliculus
    Explanation
    The Primary Visual Cortex sends information to the superior colliculus. The superior colliculus is a structure located in the midbrain that plays a role in visual processing and eye movements. It receives input from the visual cortex and helps to coordinate visual attention and orienting responses. This connection allows for the integration of visual information and the generation of appropriate motor responses based on visual stimuli.

  • 6. 

    The premotor cortex sends info to:

    • Basal ganglia

    • Cerebellum

    • Primary motor cortex

    • All of the above

    Correct Answer
    A. All of the above
    Explanation
    The premotor cortex is responsible for planning and coordinating movements. It sends information to the basal ganglia, which is involved in motor control and movement initiation. It also sends information to the cerebellum, which is important for motor learning, coordination, and balance. Additionally, the premotor cortex sends information to the primary motor cortex, which is responsible for executing voluntary movements. Therefore, the correct answer is "all of the above" because the premotor cortex sends information to all of these structures.

    • 4

    • 41

    • 17

    • 22

    Correct Answer

    Rate this question:

  • 10. 

    The primary motor cortex receives info from _____ and sends output via________.

    • Motor thalamus; corticospinal tract

    • Motor thalamus; basal ganglia

    • Sensory thalamus; corticopsinal tract

    Correct Answer
    A. Motor thalamus; corticospinal tract
    Explanation
    The primary motor cortex receives information from the motor thalamus and sends output via the corticospinal tract. The motor thalamus acts as a relay station between the primary motor cortex and other parts of the brain involved in motor control. The corticospinal tract is responsible for transmitting motor signals from the primary motor cortex to the spinal cord, which then controls voluntary movements in the body.
