Study Notes
Neuroanatomy and Nervous System Development
- The brainstem is composed of the midbrain, pons, and medulla, which convey and process signals between the body and cerebrum, regulating subconscious functions such as heart rate and breathing.
- The gray matter of the brain includes structures like the basal ganglia, amygdala, and hippocampus, responsible for neural integration and processing, and is located deep to the cerebral cortex.
- Different lobes of the brain have specific functions such as the temporal lobe for auditory processing and language, the frontal lobe for the primary motor cortex, the parietal lobe for the primary sensory cortex, and the occipital lobe for the primary visual cortex.
- The cerebellum coordinates movement and integrates sensory information to guide body responses. It consists of two lateral hemispheres connected by the vermis and has three lobes: anterior, posterior, and flocculonodular.
- The flow of cerebrospinal fluid (CSF) in the ventricles and meninges provides physical support, absorbs shock, and maintains homeostasis, with the CSF being formed in the ventricles and circulating through various channels.
- The brain's arterial supply includes two internal carotid arteries and two vertebral arteries, while dural/venous sinuses receive deoxygenated blood from the brain and drain it to the internal jugular veins.
- The spinal cord, a major reflex center and conduction pathway for efferent and afferent signals, does not always match the vertebral column and has distinct structures like the conus medullaris, cauda equina, and filum terminale.
- The development of the nervous system involves pre-embryonic stages where the fertilized ovum divides and implants into the endometrium, and embryonic stages where organs are formed, and neurons connect with the neural tube and somites.
- During the development of the nervous system, the brain undergoes various stages, including the enlargement stage, where the forebrain develops into the diencephalon and the midbrain stays midbrain, and the fetal stage from week 9 to birth, characterized by the formation of sulci and gyri.
- Myelination of neurons in the CNS and PNS occurs, with more myelinated axons leading to faster response times, and by the end of the third year, the motor and sensory systems are matured, and cerebral myelination is almost complete.
- The development of the nervous system also involves the formation of sulci and gyri in the cerebral and cerebellar hemispheres, and the maturation of the prefrontal cortex occurs around 5-7 years old, while myelination of the cerebral cortex continues until around 50 years old, aiding in integrating information and purposeful action.
