Epidermistakes
This is the outermost protective layer of the skin composed of an outer layer of dead cells
What is the epidermis
This is one of two main parts of the human skeleton, the side portions containing the bones of the arms and legs, as well as the shoulders and hipbones.
This is a structural protein that makes up the thick filaments of myofibrils.
What is myosin
This is a point where two bones meet
Joint
This narrow cavity found in the dermis is from where your hair grows
Hair follicle
This is a layer of protective hard bone tissue surrounding every bone, and is composed of repeating units of osteon systems.
Compact bone
This is a type of muscle that contracts under conscious control.
Voluntary muscle
These are thick bands of connective tissue that connect muscles to bones
Tendons
List the 2 proteins that make up each sarcomere (the contractile units of muscle fibers)
Actin + myosin
The inner, thicker portion of skin that contains blood vessels, hair follicles, and oil glands is the
What is the dermis
This is found in the humorous, femur, sternum, ribs, vertebrate, and pelvis that produces red blood cells and white blood cells.
Each section of a myofibril is called a
What is sarcomere
Between your joints you find this slippery, friction-preventing substance
What is cartilage
List the different types of burns in order from most severe to least severe
Third, second, and first-degree burns
On a cold day the blood vessels in your skin do this to retain heat
These are POTENTIAL bone-forming cells
Osteoblasts
This states that actin filaments slide toward each other during muscle contraction while the myosin filaments do not move.
The sliding filament hypothesis
This fluid filled sac is located between the bones that absorb shock and keep bones from rubbing against each other
What is the bursae
List the the two divisions of your skeleton and give an example of a bone that belong to each division.
Axial + Appendicular
This pigment cells from damage from solar radiation while this pigment is involved in the protection of cells deeper in the epidermis.
Melanin ... keratin
This is the longest bone in your body
What is the femur
This is a unit of muscle fibers composed of thick myosin protein filaments and thin actin filaments.
What is a myofibril
These burns involve the death of epidermal and dermal cells//layers and a potential loss of feeling those burned areas.
Third-degree burns
List the 3 layers of the skin from the outside to the inside
Epidermis > dermis > subcutaneous tissue
