12
The average adult human skeleton has how many bones?

What is voluntary and involuntary movement?
-Involuntary: muscle actions that is not under your control.
The integumentary system:
A. helps regulate body temperature
B. helps the body move.
C. stores minerals
D. None of the above
A
__________________ is the maintenance of a stable internal environment.
Homeostasis
-Nervous tissue
-Epithelial tissue
-Muscle tissue
-Connective tissue
Describe the skeletal system.
The skeletal system includes the bones, cartilage, and connective tissue whose primary function is to support the body.
A muscle that bends part of your body is called a _____________?
Flexor
What kind of protein does the epidermis make?
Kertain
The organ system that includes skin, hair, and nails is the _______________?
Integumentary system
Give an example of how organ systems work together.
The circulatory system and cardiovascular system work closely together to maintain homeostasis. The cardiovascular system includes the heart and blood vessels. These structures are also part of the circulatory system, which includes blood. These two systems work together to deliver the materials that cells need to survive.
Give four functions of bones.
-Protects organs
-Stores minerals
-Allows movement
-Produces blood cells
What are the three kinds of muscles?
-Smooth muscle
-Skeletal muscle
-Cardiac muscle
What protein does the dermis make?
A(n) __________________ is made up of two or more tissues working together.
Organ
Which of the following lists shows the way in which the body is organized?
A. cells, organs, organ systems, tissues
B. tissues, cells, organs, organ systems
C. cells, tissues, organs, organ systems
D. cells, tissues, organ systems, organs
C
Name the 3 different types of joints.
-Gliding Joint
-Ball-and-Socket Joint
-Hinge Joint
How do muscles move bones?
Muscles are connected to bones by tendons. When a muscle that connects two bones contracts, the bones are pulled closer together. Muscles often work in pairs.
Describe how nails grow.
A nail grows from living cells in the nail root at the base of the nail. As new cells form, the nail grows longer.
Skeletal system
Give at least four organ systems in our body.
-Integumentary system
-Muscular system
-Skeletal system
-Cardiovascular and Circulatory system
-Respiratory system
-Urinary system
-Male Reproductive system
-Female Reproductive system
-Nervous system
-Digestive system
-Lymphatic system
-Endocrine system
What are two diseases that affect the skeletal system?
-Osteoporosis
-Arthritis
Compare aerobic exercise and resistance exercise and give an example of each?
Aerobic exercise is steady, moderately intense activity, such as jogging, that improves endurance. Resistance exercise strengths skeletal muscles. During resistance exercise, muscles work against resistance, or weight.
What are two kinds of damage that may affect skin?
Damage to genetic material in skin cells can cause skin cancer. If oil glands in skin produce too much oil, hair follicles may be clogged, causing acne.
A(n) _______________ is a place where two or more bones meet.
Joint
