Document Summary
Lecture: chapter 18 brain and the cranial nerves. [brain] = portion of the cns that is contained within the cranium. 100 billion neurons + 10-15 trillion neuroglia make up the brain (each neuron forms 1000 synapses with other neurons). The brain is the center for registering sensations, correlating them with one another and with store information, making decisions, and taking actions. It is also the center for intellect, emotions, behaviour, and memory: major parts of the brain: The adult brain consists of 4 major parts: brainstem, cerebellum, diencephalon, and cerebrum. It is continuous with the spinal cord. [cere(cid:271)ellu(cid:373)] = posterior to the (cid:271)rai(cid:374)ste(cid:373), (cid:862)little (cid:271)rai(cid:374)(cid:863). [cerebrum] = supported on the diencephalon and the brainstem; the largest part of the brain: protective coverings of the brain: The cranium and the cranial meninges surround and protects the brain. [cranial meninges] are the same as around the spinal cord; they consist of: outer dura mater, middle arachnoid mater, inner pia mater.
