Study Notes
Dorsal Column Pathway
- Primary neurons in the dorsal column pathway are pseudounipolar neurons.
- Pseudounipolar neurons have a single process that divides into two branches - one going to the periphery (axon) and the other going to the CNS (dendrite).
Nerve Fascicles
- Nerve fascicles are surrounded by the perineurium, a layer of connective tissue that helps to protect and organize the nerve fibers.
Spinal Cord Development
- The alar plate of the developing spinal cord will contain sensory neurons.
- The basal plate of the developing spinal cord will contain motor neurons.
Subdivisions of the CNS
- The image provided should indicate a part of the central nervous system.
- The central nervous system consists of the brain and spinal cord.
Association Areas
- The parietal lobe is responsible for sensory integration, including the association of touch, pressure, pain, and temperature.
- Therefore, remembering the texture of a pet's hair is a function of the parietal lobe's association area.
Breathing Regulation
- The medulla oblongata works with the pons to regulate the rate of breathing.
Foot Drop
- Foot drop, a condition causing weakness in dorsiflexing the ankle and toes, can be associated with damage to the common fibular nerve or deep fibular nerve.
- The common fibular nerve is responsible for innervating the muscles that dorsiflex the foot and extend the toes.
CSF Flow
- The lateral ventricles connect to the third ventricle through the interventricular foramina of Monro.
- CSF then flows through the third ventricle, down the cerebral aqueduct, and into the fourth ventricle.
Space at the Arrow Tip
- The image should indicate the subarachnoid space, the space between the arachnoid mater and the pia mater.
- The subarachnoid space contains cerebrospinal fluid (CSF).
