Study Notes
Neurology Basics
- Frontal Lobe: responsible for executive function, including behavior, mood, emotion, concentration, sequencing, personality, social behavior, planning, organizing, and reasoning/problem-solving.
- Frontal Lobe: Broca's area is responsible for expressive speech, and damage to this area can result in difficulty speaking.
Temporal Lobe
- Responsible for hearing, attention, and retaining new information.
- Involved in short and long-term memory storage.
- Helps to understand speech and language.
- Also involved in sexual behavior.
- Wernicke's area is responsible for receptive speech, and damage to this area can result in difficulty understanding conversations.
Parietal Lobe
- Responsible for sensations, including proprioception of body parts, temperature, pressure, touch, smell, pain, and taste.
- Also involved in attention and mathematics.
Occipital Lobe
- Responsible for processing visual inputs, including color, forms, motions, words, and locations of objects.
Cerebellum
- Responsible for fine movements, rapid movements, walking, and grabbing objects.
Brain Stem
- Responsible for breathing, swallowing, balance, movement, and consciousness.
Brain Facts
- Nervous system crosses in the Medulla.
- The right brain controls the left side of the body, and the left brain controls the right side of the body.
Albumin
- Most abundant plasma protein in blood, making up ~50% of protein in blood.
- Synthesized by hepatocytes.
- Maintains intravascular oncotic pressure.
- Carries hormones, ions, and medications.
Causes of Hypoalbuminemia
- Renal loss.
- Gut loss.
- Intravascular volume expansion.
- Decreased albumin production.
- Sepsis and critical illness.
- Heart failure.
- Burns.
- Nutritional deficiency.

- Dehydration.
- Metabolic syndrome.
- Insulin resistance.
Anatomy Fun Facts
Brain
- The average brain weighs three pounds.
- The brain uses cells called neurons to send messages to the rest of the body at 150-200 miles per hour.
- The brain stops growing at age 18, but learning continues.
Heart
- The average heart weighs one pound.
- The heart beats an average of 115,000 times a day and pumps about 2,000 gallons of blood a day.
Lungs
- The left lung is slightly smaller than the right to make room for the heart.
- The right lung is divided into three sections called lobes.
- The left lung has two lobes.
- The average adult takes about 12-20 breaths a minute when at rest, and breathes about 11,000 liters of air a day.
Kidneys
- The kidneys measure about 4.5 inches long and work to purify blood and eliminate waste in the body.
- The blood flow to the kidneys is higher than the blood flow to the liver, brain, and even the heart.
- The kidneys purify all the blood in the entire body about 400 times a day using tiny filters called nephrons.
Stomach
- An adult stomach can hold up to half a pound of food and drink.
- The stomach produces hydrochloric acid to kill any bacteria or viruses that may enter the body through the food.
Liver
- The liver performs over 500 different functions.
- The liver filters toxins out of the blood, makes and stores fuel in the form of glucose, and produces a digestive juice called bile that helps the body process fat.
Intestines
- The small intestines digest food and absorb vitamins and nutrients, taking between 1-4 hours.
- The large intestine absorbs water before eliminating waste.
