Study Notes
Cranial Nerves
- Hypoglossal Nerve (Cranial Nerve XII): Responsible for motor control of the tongue, facilitating movement necessary for speech and swallowing.
- Facial Nerve (Cranial Nerve VII): Responsible for motor control of the facial muscles, allowing for expressions and movements such as smiling and frowning.
Sensory Pathways
- Spinothalamic Tract: Transmits information related to touch, temperature, and pain from the body to the brain, playing a crucial role in sensory perception.
Motor Pathways
- Corticospinal Tract: Responsible for voluntary movement and fine motor control of the limbs, originating from the cerebral cortex and traveling down to the spinal cord.
Neuron Types
- Lower Motor Neurons: Located in the spinal cord or brainstem, these neurons carry signals from upper motor neurons to the muscles, facilitating muscle contraction and movement.
- Upper Motor Neurons: Located in the cerebral cortex, these neurons carry signals from the brain to the spinal cord or brainstem, initiating voluntary movements.
