What is the uppermost and largest bone of the arm, extending from the elbow to the shoulder?

What consists of the brain, spinal cord, spinal nerves, and cranial nerves. It controls consciousness and many mental activities, voluntary functions of the five senses (seeing, hearing, feeling, smelling, and tasting), and voluntary muscle actions, including all body movements and facial expressions?

What is a large, flat triangular muscle covering the lower back?

What sends the blood from the heart to the lungs to be purified, then back to the heart again?

What is made up of lymph, lymph nodes, the thymus gland, the spleen, and lymph vessels that act as an aid to the blood system?

What is the longer bone of the forearm. It is larger at the elbow than at the wrist and is located on the little finger side of the hand?

What is a system of nerves that connects the peripheral (outer) parts of the body to the CNS; it has both sensory and motor nerves. Its function is to carry impulses, or messages, to and from the CNS?

What is the muscle that covers the back of the neck and upper and middle region of the back; rotates and controls swinging movements of the arm?

What carries the blood from the heart throughout the body and back to the heart. The following is an overview of how these systems work?

What produces a substance that travels through small, tube-like ducts. Sweat and oil glands of the skin belong to this group?

What is the shorter of the two bones of the forearm. It is largest at the wrist and is located on the thumb side of the hand?

What is the part of the nervous system that controls the involuntary muscles; it regulates the action of the smooth muscles, glands, blood vessels, heart and even normal breathing?

What are the muscles that separate the fingers?

What are thick-walled, flexible tubes that carry oxygenated blood away from the heart to the capillaries?

What is the most complex organ of endocrine system. It affects almost every physiologic process of the body: growth, blood pressure, contractions during childbirth, breast milk production, sex organ functions in both women and men, and thyroid gland function, the conversion of food into energy (metabolism)?

What is the heavy, long bone that forms the leg above the knee?

What supplies impulses to the skin of the inner side of the leg and foot?

What muscle covers the outer side of the calf and inverts the foot and turns it outward?

What are tiny, thin-walled blood vessels that connect the smaller arteries to the veins. They bring nutrients to the cells and carry away waste materials?

What controls how quickly the body burns energy (metabolism), makes proteins, and how sensitive the body should be to other hormones?

What is also called the accessory bone, forms the cap of the knee joint?

What is a division of the sciatic nerve, passes behind the knee. It subdivides and supplies impulses to the knee, the muscles of the calf, the skin of the leg, and the sole, heel, and underside of the toes?

What is the large, triangular muscle covering the shoulder joint that allows the arm to extend outward and to the side of the body?

What are thin-walled blood vessels that are less flexible than arteries. They contain cup-like valves that prevent backflow and carry blood containing waste products from the capillaries back to the heart and lungs for cleaning and to pick up oxygen?

What secretes about 30 steroid hormones and control metabolic processes of the body, including the flight-or-flight response?
