Document Summary
Collections of neurons: gray matter generic terms for collections of cell bodies in the cns. Stuff in middle of spinal cord: cortex (cid:373)ea(cid:374)s (cid:862)o(cid:374) the outside(cid:863, nucleus central core, describes the centre of things. For neuroanatomy distinct mass of neurons, usually deep in the brain clustered neurons: substantia, used for groups of related neurons with less distinct borders of nuclei, more diffuse orders, locus. Small, well-defined group of cells: essentially, a tiny nucleus, ganglion, collection of neurons in the pns, collections of cell bodies in pns. Internal capsule connects brain stem to cortex: commissure, connects one side of the brain with the other, ex. Corpus callosum: lemniscus, tract that meanders through the brain like a ribbon. Initially collection of indifferentiated cells after fertilization. Invagination and folding end up with 3 layers: endoderm orange, visceral organs, gut organs, mesoderm red, ectoderm blue, gives rise to bones and muscle, nervous system and skin. Early nervous system: dorsal view, top of picture anterior.
