A brain surgeon removed a piece of a woman’s skull and cut through all the meninges to reach the brain itself. Name all the layers that were cut, from skin to brain.

What type of cut would separate the brain into anterior andposterior parts?

The four hollow and interconnected spaces within the brain are called the    a) meninges  b) humours  c) ventricles  d) pons

The brain stem connects the brain to the spinal cord. It kind of looks like a tail coming out the back. It includes three parts including the posterior-most _5__, the bulb-like _6__ and anterior-most _7__. This region of the brain contains centers for breathing and heart rate. It also serves as a relay station for nerve impulses traveling between the brain and the spinal cord.

Lumbar Puncture or Spinal Tap During a spinal tap, what structures does the needle go through? Start with the outer part of the skin and work your way in. Also, CROSS OFF the structures or spaces that the needle does NOT reach. hypodermis arachnoid mater dermis dura mater epidermis epidural space subdural space pia mater spinal cord subarachnoid space Describe the structure and function of the blood-brain barrier.

The “big portion of the brain” that the narrator highlights first is the __1__. This area is responsible for higher mental functions.    Notice that there are visible folds (“bumps and grooves”) on this structure.  Each elevated bump is called a __2_ while each shallow groove is called a __3_. Located at the “back of the brain” is the __4_____.  In the longitudinal cut you are looking at, you’ll notice that it has an internal, tree-like pattern called arbor vitae.  This part of the brain coordinates equilibrium and motor activity to produce smooth, controlled movements.   The brain stem connects the brain to the spinal cord.  It kind of looks like a tail coming out the back.  It includes three parts including the posterior-most _5__, the bulb-like _6__ and anterior-most _7__.  This region of the brain contains centers for breathing and heart rate.  It also serves as a relay station for nerve impulses traveling between the brain and the spinal cord.   As our narrator moves…

Which of the following anatomical or physiological terms would apply to the brain? 1. superior 2. pump 3. neuron 4. abdominal 5. control center 6. action potential 7. cardiovascular system 1, 3, 4, 7 2, 4, 6 1, 2, 4, 5, 7 1, 3, 5, 6 2, 7

During your dissection of the brain, you divided the brain into equal right and left portions. Which plane did you cut along?

Galen performed vivisection, or live experimentation, on animals to learn about the nervous system. What did Galen discover with his squealing pig experiment? A) Galen correctly identified that peripheral nerves could control bodily function B) Galen correctly identified the division between the central and peripheral nervous systems C) Galen demonstrated that tendons, ligaments and nerves were separate entities D) Galen demonstated that transection of individual nerves had little functional consequence.

The part of the human brain that distinguishes us most from less complex animals is the:     old brain     limbic system     cerebral cortex     brain stem
