Musculoskeletal System
Control
Nervous System
Engine
Cardiorespiratory System
Study of the structure, shape, size, weight, and location of all the organs of the human body
Human Anatomy
Study of all the systems of the human body, their functionsfunctions, and their relationship with other systems
Human Physiology
Composed of ____ bones at birth;
270
decreases to ___ bones by adulthood
206
Functions of the Skeleton
- protects internal organs
- stores and releases fat
- produces blood cells
- stores and releases minerals
- facilitates movement
- supports the body
Point of contact between two bones, and cartilage, or between bone and teeth in the skeleton of the body
Joint
Types of Joints
Fixed, cartilaginous, synovial
Musculoskeletal System is consist of:
• Skeletal system
• Skeletal muscles
• Ligaments
• Tendons
• Cartilage
bones and joints
Skeletal system
Skeletal muscles
voluntary
ligaments
connects bones to bones
connect muscles to bones
tendons
shock-absorbing gel between joints
Cartilage
Functions of muscles
•Movement
•Protects organs
•Thermogenesis
•Blood circulation
•Respiration
Functions of nervous system
•Controls all body’s activities •Receives information about environment
•Stores memories
•Allows thinking and learning
Provide most of the unique functions of the nervous system
neurons
Enables breathing in of Oxygen and releasing of Carbon dioxide
respiratory system
The expulsion of air from the lungs through contraction of the chest cavity
exhalation
The intake of air into the lungs through expansion of the chest cavity
inhalation
Functions of the Respiratory System
•Oxygen Delivery
•Filters, warms, and humidifies inhaled air
•Speech and sense of smell
number of breaths per minute
breath rate
ex: at rest (12-20 bpm), physical activity (30-50 bpm)
maximum amount of air that can fill the lungs
lung capacity
ex: non smoker (3-4 L), smoker (1-1.5 L), athlete (7L)
contains the Heart, Blood vessels (arteries, veins, capillaries) , Blood
Cardiovascular system
max heart rate
=220 - age
resting heart rate
sedentary- 60-90 bpm
athletes- 40-60 bpm
When the angle between two body parts is decreased
Flexion
When the angle between two body parts is increased
Extension
Extension past the anatomical position
Hyperextension
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 upward
supination
when the forearm is rotated so that the palm is facing downward
pronation
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
