Chapter 45
The lungs are located in the
Abdominal cavity.
A skin disorder caused by blockage of oil glands is called
Acne.
Actin and myosin
Are found in the sarcomere section, are proteins, interact during muscle contraction.
Muscle tissue functions to move
Blood, food in the digestive tract, and bones.
Smooth muscle
Can chafen the diameter of blood vessels, moves food through the digestive tract, is not under conscious control.
The heart and the blood vessels are separate organs that form the
Cardiovascular system.
What is the difference between cartilage and bone?
Cartilage contains cells that can continue to divide and grow, while bone does not.
In a fetus, most bones are originally made of
Cartilage.
From the smallest functional units to the largest, the body is organized as follows:
Cell, tissue, organ, system, body
The type of bone that provides the greatest strength for support is
Compact bone
Human skeleton : internal organs ::
Construction worker's hard hat : construction worker's head
The functions of the skin include
Defense against microbes, regulation of body temperature, and prevent of dehydration.
The total amount of force that a muscle exerts
Depends on the total number of individual muscle fibers that have been stimulated.
Tissue that is specialized to cover the inner and outer surfaces of the internal organs is called
Epithelial tissue
Flexors : Ben ::
Extensions : straighten
Energy reserves are stored in the skin as
Fat cells.
Muscle that bend joints are categorized as
Flexors.
Smooth muscle can be found
In internal organs.
The dermis of the skin is
Involved in temperature regulation.
Keratin
Is a protein.
The origin of a muscle
Is at the opposite end of the muscle from the insertion, is located on a bone that remains stationary when the muscle contracts, does not move when the muscle contracts.
Compact bone : periosteum ::
Marrow : compact bone
Tendons connect
Muscle to bone
Ligaments attach
Muscle to muscle.
Tightly connected cells that are arranged in flat sheets are characteristic of
Nervous tissue
The insertion of a muscle
None of the above.
Organs that work together from
Organ systems.
Degeneration of cartilage causes
Osteoarthritis
The skin performs all of the following except
Production of chemical messengers.
Yellow bone marrow
Provides support to spongy bone.
A muscle can
Pull a bone.
Muscles exert force by
Pulling on surrounding tissues.
Which of the following is a function of both the excretory system and the digestive system?
Regulating other organ systems
The heart and lungs are protected by the
Rib cage.
The region between Z lines is called the
Sarcomere.
Repeating units of myosin and actin filaments bound by two Z lines are
Sarcomeres.
The three types of muscles are
Skeletal, smooth, and cardiac.
The periosteum is a section of the bone that contains
Spongy bone.
Connective tissues include
Tendons that connect muscle to bone, the layer beneath your skin that connects the skin to muscle, fat.
The thin outer layer of the skin is
The epidermis.
Which of the following is not part of the axial skeleton?
The rib cage.
Blood, bone, and cartilage are examples of
Three different tissue types found in the body.
A person with a broken pelvis would probably be unable to
Walk.
The point where two or more bones meet is called
a joint.
