The scientific study of the structure function and pathology of the nervous system ____

Neurology

_____ the largest most complex nerve tissue in the body. Located in cranium weighs less than 3Ib controls sense s muscles glands thoughts feelings travels messages through 12 cranial nerves.

_____portion of CNS originates in brain extends to lower trunk and protected by spinal column. 31 pairs of spinal nerves extend off the spinal cord to the muscles and skin of trunk and limbs

Brain

Spinal cord

_______ send impulses away from the cell body (neuron) to other neurons glands or muscles. Nerves originate in brain/spinal cord and send branches to body.

Axon terminal

______ carry impulses or messages from the sense organs to the brain where touch Cold heat sight hear taste smell pain and pressure are experienced.

Receive info through receptors “sensory nerve endings”

_____ carry impulses away(exit)

Sensory afferent nerves

Motor nerves efferent nerves

_____nerve supplies the fingers. _____nerve supplies the thumb side of arm and back of hands.

Digital

Radial

_____nerve is a division of sciatic nerve. Passes behind knee. Supplies impulse to knee calf skin sole heel and under toes.

____also a division of sciatic nerve extends from knee to around head of fibula where it divides into deep Peroneal nerve “anterior nerve” & superficial peroneal nerve “musculocutaneous nerve”

____ supplies impulses to the Skin on the outer side and back of foot and leg

Tibial nerve

Common peroneal nerve

Surat nerve

Circulatory system made of two divisions _____consists of heart arteries veins capillaries

____AIDS the blood system. Helps carry waste away from cells and routed back to circula Tory system.

Blood vascular system

Length vascular system

___Is enclosed by a double layered membranous known as the____ Which is made of epithelial tissue. It’s approximately the size of a closed fist it’s heartbeat is regulated by the Vagus nerve. And nerves in the ANS. Has four chambers the upper right atrium the left atrium were blood is pumped to the ventricles and the two lower right and left ventricles

Heart | pericardium

Deoxygenated blood flows into the right atrium through the tricuspid valve into the right ventricle which pumps into the pulmonary arteries through the lungs releasing gases and replacing it with oxygen. 4. That’s oxygen rich blood returns to the heart through the pulmonary ____ and enters the ____. 5. From the left atrium the blood flows through the _____ valve or bicuspid valve and into the ______. The blood then leaves the ventricle and travels to the body.

Veins, let atrium | Mitral, left ventricle.

___Thick walled flexible carry oxygen away from the heart to the capillaries third largest is the aorta the aerial trunk that carries blood from the heart to the arteries through the body. ___Are thin walled blood vessels less flexible contain cup like valves that prevent backflow and carry waste from capillaries back to the heart and lungs located more superficial.

Arteries | Veins

__Is a nutritive fluid that supplies oxygen and nutrients to cells and tissues and removes carbon dioxide and waste approximately ____ pints blood in the human body which is 1/20 of its weight. Blood is approximately ____% water sticky and salty temperature of 98.6° bright red in the arteries and dark in the veins colors change with exchange of carbon dioxide for oxygen blue blood is Oxygen poor and red blood is rich in oxygen

Blood, 8-10, 80

Composition of blood: ____Are produced in the red bone marrow and contain _____ an iron containing proteins that temporary binds with oxygen to carry it from the lungs to the body and transport carbon dioxide from the cells to the lungs. ___Also called leukocytes destroy disease causing microorganisms ____Much smaller than red blood cells contribute to the blood clotting process Fluid part of the blood we’re red and white blood cells and platelets flow it’s about 90% water and contains proteins and sugars carries food and nutrients to the cells and removes carbon dioxide from cells

Red blood cells, Hemoglobin White blood cells Platelets Plasma

Blood helps to equalize the bodies temperature does protecting from extreme heat or cold also sells leaks in injured blood vessels by forming clots to prevent blood loss.

___Supplies blood to the foot divides into two separate arteries Known as the anterior tibial artery and posterior tibial artery. ___Supplies blood to lower leg muscles and skin on top of the foot and adjacent sides of the first and second toes this artery goes to the foot and becomes dorsalis pedis artery

Popliteal artery Anterior tibial artery

___Is made up of length lymph nodes the time is gland the spleen and lymph vessels that aid the blood system. Length is colorless and watery derived from blood plasma that has filtered through the capillary walls into the tissue space. It protects the body from disease develops immunity‘s and drains tissue spaces of excess interstitial fluid to the blood. Carries waste away from cells

Lymphatic immune system

___Is a group of glands that affect growth development the health of the entire body and sexual activities.Glands are special organs that remove certain elements from the blood to convert them into new compounds there are exocrine (duct) glands -sweat /oil and endocrine (ductless) glands- thyroid or pituitary release hormones.

Endocrine system

List of endocrine glands: _____Plays a major role in sexual development , sleep and metabolism. _____Is the most complex of the endocrine system affects every physiologic process like growth, blood pressure, contractions during childbirth, breast milk production, sex organ functions in both genders and thyroid gland function the conversion of food into energy metabolism. _____Controls how quickly the body burns energy makes proteins and how sensitive the body should be to other hormones. ___Regulates blood calcium and phosphorus levels so the nervous and muscular system can function properly. The pancreas secretes enzyme producing cells for digestion adrenal glands secrete steroid hormones for the metabolic processes and the flight or flight response. Ovaries and testes determine sexual characteristics.

Pineal gland Pituitary gland Thyroid gland Parathyroid glands

____Is responsible for purifying the body by eliminating waste metabolism of body cells forms toxic substances that could poison our body. The following organs play a role in this system. The kidneys excrete waist through urine. Liver discharges waist containing bile. Bile. The skin illuminates waist through ____. The large intestine illuminates decomposed and undigested food. The lungs exhale CO2 and other gases like formaldehyde a byproduct of metabolism used to build important substances.

Excretory system, Perspiration

Oxygen is more essential than either food or water people can survive 60 days without food and several days without water but if deprived of oxygen will die within minutes
