Cartilage
Functions of Muscles:
MPTBR
Movement
Protect organs
Thermogenesis
Blood ciruclation
Respiration
Functions of nervous system
CRSA
Controls all body’s activities
Receives information about environment
• Stores memories
• Allows thinking and learning
The neuron possess _____
Electrical Excitability
It provides most of the unique functions of the nervous system
Neuron
Enables breathing in of Oxygen and releasing of Carbon dioxide
Respiratory system
Mechanism or Respiration
Inhalation and Exhalation
The intake of air into the
lungs through expansion
of the chest cavity
Inhalation
The expulsion of air from the lungs through
contraction
of the chest cavity
Exhalation
Who had the longest breathing in history and how mang minutws
Budimir Buds Obote, 24:33
54 years old
Functions of Respiratory System
OFS

Types of movements
F,E,HE,AB,AD,R,C,PRO,SUP, DOR,PLAN, rad, uln, opp
Flexion, extension,hyperextension,abduction,adduction,rotation, circumduction,pronation,supination,dorsiflexion,plantar flexion, radial deviation, ulnar deviation and opposition
When the angle between two body parts is decreased
Flexion
When the angle between two body parts is increased
Extension
Movement away from an imaginary midline of the body
Abduction
Movement toward an imaginary midline of the body
Adduction
When a bone rotates toward the midline (medial) or away from the midline (lateral) of the body
Rotation
Circular movement of a limb or body part
Only possible for ball and
socket joints
Circumduction
when the forearm is rotated so that the palm is facing downward
Pronation
When the forearm is rotated so that the palm is facing upward
Supination
When the toes are pointing toward the tibia
Dorsiflexion
When the toes are pointed downward and the heel is raised
Plantar flexion
Movement of the wrist toward the radius
Radial deviation
Movement of the wrist toward the ulna
Ulnar deviation
Movement of the thumb across the palm of the hand
Opposition
