100
Stand in the correct anatomical position.
What is flat-footed, facing forward, arms with palms forward.
100
Name the four types of tissues.
What are epithelial, connective, muscular, and nervous.
100
Name the three layers of the integumentary system in order from superficial to deep.
What is the epidermis, dermis, and subcutaneous layer.
100
What are the main components of compact bone tissue?
What are osteons.
100
Name 2 of the 4 functions of muscle tissue
Movement, Posture, Body heat, as smooth muscle in other systems
200
The right leg is ______________ to the left arm.
What is contralateral.
200
Simple Epithelial tissue has how many layers?
what is one?
200
Explain what causes skin color.
What is: melanin is made by melanocytes, and there are different types of melanin that have different pigments to show different skin colors.
200
Name two of the 3 types of bone tissue cells and describe their function.
What are: osteoblasts build bone tissue, osteoclasts break down bone tissue, and osteocytes are mature bone cells.
200
Give an example of a striated voluntary muscle
any skeletal muscle
300
What is another name for the backside?
What is dorsal.
300
Connective tissue is comprised of these 3 parts
What are protein fibers, specialized cells, and ground substance.
300
Describe three functions of the integumentary system.
What is: thermoregulation, blood reservoir, protection, cutaneous sensations, excretion and absorption, and synthesis of vitamin D.
300
Describe three functions of the skeletal system.
What is: support, protection, assistance in movement, mineral homeostasis, blood cell production, and triglyceride storage.
300
Place the following muscle structures in order from smallest to largest:
myofilament, Fascicle, myofiber, muscle belly
myofilament, myofiber, fascicle, muscle belly
400
The plane shown in the diagram
What is sagittal? (midsagittal)
400
Two structural features that would allow me to identify cardiac tissue from smooth muscle tissue
branching, intercalated discs, striations
400
Name the types of tissues that make up each layer of the integumentary system.
What is: the epidermis is epithelial tissue, the dermis is connective tissue, and the subcutaneous layer is adipose tissue (connective tissue.)
400
The structure pictured and its purpose
Epiphyseal Plate--for growth
400
Explain the difference between the origin and insertion of a muscle.
What is the origin is the attachment site for the stationary bone and the insertion is the attachment site on the movable bone.
500
Name the 2 body systems that are responsible for initiating response to the environment.
What are endocrine and nervous system?
500
Name 4 of the connective tissues that we discussed.
What is loose connective tissue, dense connective tissue, cartilage, bone tissue, and liquid connective tissue. (others acceptable)
500
What is keratinization and what is its importance?
What is: keratinization is the process where the protein keratin is laid down in epidermal cells. It is important because it is used for protection for skin cells.
500
Describe the process of intramembranous ossification
What is osteoblasts form from mesenchymal cells. They cluster in ossification centers laying collagen. Collagen gains minerals and hardens. Spongy bone forms along the center and compact forms along the sides of the bone near the osteoblasts.
500
Describe in detail how muscle contraction occurs.
What is actin and myosin connect and form crossbridges when calcium is released from a muscle fiber. The actin and myosin slide past each other, which decreases the length of the sarcomere and of the entire muscle.
