Nervous System Flashcards
Which cranial nerve is for hearing and balance
Cranial nerve XII
The study of the structure of the body and its parts is called
Anatomy
How much air do we exchange during a normal cycle of breathing in and out
500ml
When do girls puberty usually begin
Age 10 to 11
What conditions would be most dangerous for a patient
Ventricular fibrillation
Aldosterone is released from the adrenal cortex to regulate
Salt levels
What is the basic structure and functional units of the body
Cells
Muscle cells generate ATP by burning fuel (glucose) and oxygen in a process called
Aerobic respiration
Antibodies are produced by
Plasma cells
How many muscles and bones are in the human body
600 muscles and 206 bones
Etiology
The study of organs and causes of diseases
What are the 6 levels of structural organization
Chemical - atoms and molecules
Cellular - cells and their organelles
Tissue - groups of similar cells
Organ level - consist of 2 or more types of tissue
Organ system - organs that work closely together
Organismal - all organs system
What are the 11 organ systems
Integumentary system
Skeletal system
Muscular system
Nervous system
Endocrine system
Cardiovascular system
Lymphatic system
Respiratory system
Digestive system
Urinary system
Reproductive system
What is the rule of 9
Head 9%
Upper limb (arm) 9%
Front and Back of the trunk 18%
Front of the chest 9%
Back (upper and lower) 9%
Anogenital area 1%
Lower leg 9% (both 18%)
What is the main function of the skeleton
Protection of the brain, spinal cord, and internal organs. Support for the body and soft organs. Levers for muscle action and movement. Storage of mineral (calcium and phosphorus). Blood cell formation in red bone marrow. Fat storage in yellow bone marrow.
muscle tissue
The only tissue in he body that convert chemical energy o mechanical energy
Excitability
The ability for muscle tissue to receive nerve stimuli and respond to them by contracting
Contractability
The ability for the muscle tissue to shorten when stimulated
Extensibility
The ability for the muscle tissue to be stretched
Elasticity
The ability for muscle tissue to recoil to resting length
Central nervous system
CNS consist of the brain and the spinal cord
Peripheral nervous system
PNS consist of crainal and the spinal nerves that convey messages to and from the CNS
The Brain
Divided in to 4 part:
Cerebral hemisphere
Diencephalon
Brain stem
Cerebellum
Cerebrum
The site of our conscious mind, awareness, sensory perception, voluntary motion, imitation, communication, memory storage and understanding
Diencephalon
Center emotional response and autonomic control center for functions such as blood pressure, body tempature, sleep-awake cycle and water balance
What are the basic functions of the nervous system
Gather information via sensory receptors
Analyze information
Activate effector organs
Spinal cord
Spinal cord is the part of the central nervous system inside the vertebral canal below the skull
Olfactory
Smell I
Optic
Sight II
Oculomotor
Eye movement III
Trochlear
Eye movement IV
Trigeminal
Somatosensory information (touch, pain) from the face and head; muscle for chewing V
Abducens
Eye movement VI
Facial
Taste VII
Vestibulocochlear
Hearing ; balance VII
Glossopharyngeal
Taste IX
Vagus
Sensory, motor and autonomic function of viscera (glands, digestion, heart) X
Spinal accessory
Controls muscle used in head movement XI
Hypoglossal
Controls muscle of the tongue XII
