Brains, I need brains!

So last semester, our big class was functional anatomy (= the whole body). This semester, we are focusing on neuroanatomy and neurobiology (= brain, spinal cord, nerves, etc.). We'll be dissecting a bunch of brains during our labs, including canine and ovine (sheep) brains.

Above is an example of a canine brain. All of the squiggly fleshy looking parts are called gyri (singular = gyrus). The indentations dividing the gyri are called sulci (singular = sulcus). On the dog brain, we are supposed to learn all of the gyri and all of the sulci. They have awesome names like pseudo-sylvian sulcus (say that 5 times fast) and suprasylvian gyrus.
But at least we don't have to learn the gyri and sulci on the human brain! Makes me glad I'm in vet anatomy. See the human brain below:



Yikes!
