Organization of the body into parts (head, trunk and neck) and paired upper and lower limbs
What is the emphasis of regional anatomy?
Placed on the relationship of various systematic structures like muscles, nerves, and arteries
What is an essential part of the regional anatomy approach?
Surface anatomy (providing a knowledge of what structures are visible or palpable)
What is systematic anatomy?
Based on the organization of tissues and organs of the body according to mutual functions
How do organ systems never function?
In isolation
Integumentary system
Consists of skin and its appendages (hair and nails)
Skeletal system
Bones and cartilage (provides support for the body and protects vital organs)
Articular system
Joints and their associated ligaments (connects the bony parts of skeletal system and provides sites where movements occur)
Muscular system
Muscles that act to move or position parts of the body
What does the Nervous system consist of?
Consists of CNS (brain and spinal cord) and PNS (nerves and ganglia together with their motor and sensory endings)
What does the nervous system control?
Control and coordinates the function of organ systems
What does the circulatory system consist of?
Cardiovascular and lymphatic systems
What is the function of the circulatory system?
Distribute fluids within the body
What does the cardiovascular system consist of?
Heart and blood vessels
What is the function of the cardiovascular system?
Propel and conduct blood through the body
What does the lymphatic system consist of?
A network of lymphatic vessels
What is the function of the lymphatic system?
Withdraw excess tissue fluid from the body’s interstitial fluid compartment and filters it though lymph nodes and returns it to the blood stream
What does the digestive or alimentary system consist of?
Organs and glands associated with ingestion, mastication, deglutition, digestion, and absorption of food
What does the respiratory system consist of?
