Integumentary system (Aka your skin)
• Main Functions of the Integumentary system
– Protection
• Bacteria
• UV light
• Physical insult
– Prevents Dehydration
• Keratin (protein that waterproofs the skin)
– Heat Control
– Regulate Body Temperature
– Vitamin D Production
• Epidermis
– Mostly dead cells ( your outer skin is dead and flakes off_
– Cytoplasm is filled with keratin
• Dermis
– Blood vessels
– Loose Connective tissue
– Dense Connective tissue
• Collagen and elastic fibers
• Wrinkles happen when elastin protein breaks down
• Hypodermis (not skin)
– Loose Connective
• Adipose (this is fat)
,Skeletal system
• Four Main Functions
– Support
– Movement
• Attachment of muscles
– Protection
• Skull Brain
– Storage of Minerals
• Ca and P
Inner bone structure
• Periosteum (think of the skin surrounding the bone on a chicken wing)
– Membrane on the outside of bone
– Nourishes bone (nutrients, blood, oxygen)
• Compact Bone ( the outer shell of a bone)
– on the surface
• Compact bone is made up Osteons ( which are structured like tree rings)
• Osteons have:
– Central Canal
• Blood vessels
• Nerve
Osteocytes –mature bone cells
• Spongy Bone – is the middle of the bone and has two types of bone marrow
• Red Bone Marrow
– Hematopoietic
• Red blood cells
, • White Blood Cells
• Platelets
– Mesenchymal
• Osteocytes and chondrocytes
• Yellow Bone Marrow
– Fat Storage
Joints
• Fibrous Joints
– Sutures in skull
• Cartilaginous Joints
– Ribs to sternum
– Pubic symphysis in child birth (cartilage to collape when going through the birth canal)
• Synovial Joints (knee, hip, elbow, ankle, others)
– Synovial membrane
– Cartilage
– Ligaments (dense connective) hold bones
Bones to know for the TEAS V
1) On yourself, locate the following:
a. Patella – also known as the knee cap
b. Tibia – the large bone in your shin (lower leg)
c. Fibula – the small bone in your shin (lower leg)
d. Talus – the bone at the base of your anterior shin
e. Femur – The largest bone in your leg (thigh)
f. Humerus – the largest bone in your arm
g. Ulna – of the two bones in your forearm, this is on your little finger side
h. Radius – of the two bones in your forearm, this is on your thumb side
i. Scapula – the shoulder blade
j. Os coxa – the pelvic bone or hip
k. Calcaneus – the ball of your ankle
l. Sternum – at the midline of your body over the heart and between the lungs
m. Clavicle – the collar bone
