Study Notes
Brain Anatomy Overview
- The brain can be divided into different parts: forebrain, midbrain, and hindbrain.
- The forebrain consists of the telencephalon and diencephalon, forming the prosencephalon.
- The midbrain is referred to as the mesencephalon, and the hindbrain as the rhombencephalon, which can be divided into the metencephalon and myelencephalon.
- These divisions are derived from primary brain vesicles that emerged during early brain development.
- The spinal cord connects the periphery to the brain and consists of 30 spinal segments, each with gray and white matter.
- Gray matter in the spinal cord consists of cell bodies, while white matter consists of nerve connections.
- The spinal cord has a butterfly-like shape with different horns and laminae.
- The orientation of the brain and spinal cord are not the same, with a 90-degree shift in humans compared to other animal species.
- Terms for orientation include superior/dorsal, inferior/ventral, posterior/caudal, and anterior/rostral.
- Different planes yield different sections of the brain, such as coronal sections when looking at things from the front.
- The cerebellum is part of the metencephalon, while the pons and medulla oblongata are part of the brain stem.
- The brain stem, midbrain, and hindbrain together constitute the CNS, and the spinal cord plays a crucial role in passing information in a bi-directional fashion.
Neuroanatomy and Brain Structures
- The insula functions to add emotional context to sensory input and links sensory information and emotions.
- Sulci, fissures, and gyri have specific names that make sense, like the parietal archipelul sulcus and the central sulcus.
- The longitudinal fissure separates the left and right hemispheres of the brain.
- The pre-central gyrus is located in front of the central fissure, while the post-central gyrus is located behind it.
- The brain's midline is the longitudinal fissure, and gyri are the brain tissue coils, while grooves between gyri are called sulci.
- The bulbous olfatorius deals with olfaction and constitutes about 10% of the total brain volume in rodents.
- The optic chiasm is the crossing of nerves from the eyes to the brain, with the left brain hemisphere processing information from the right side of the body and vice versa.
- The corpus callosum is a collection of fibers that connect the left and right brain hemispheres, mediating communication between them.
- The commissure anterior and commissure posterior are smaller fiber tracks that also connect the left and right brain hemispheres.
- The ventricular system contains cerebral spinal fluid, which mediates buoyancy, protects the brain from trauma, provides nutrients, and eliminates waste products.
- Cerebral spinal fluid is located between the skull and the brain, serving to protect the brain from impacts and trauma.
- The ventricular system has various functions, including mediating buoyancy, protecting the brain from trauma, providing nutrients, and eliminating waste products.
Neuroanatomy Lecture Summary
