What are the three types of muscle?10 points
What is a functional unit of a striated muscle cell?
20 points
What are the major proteins in the 2 types of myofilaments?
30 points
Describe the structural differences between the two
structures that make up a myofibril.40 points

10 points
Sarcomere
20 points
Myosin (thick myofilaments) & Actin (thin myofilaments)
30 points
The actin proteins are thin filaments which consist of two chains of actin proteins wound around each other
(they also contain the proteins troponin attached to tropomyosin).
The myosin are thick filaments made up of two long chains of myosin molecules with a globular head at
one end.
40 points
On the thin filaments, Ca2+ ions bind to troponin, causing the tropomyosin molecules to shift, exposing myosin binding sites, allowing cross bridges to form between the myosin and actin. As the cross bridges break and reform and break again, the muscle contracts. Muscle contracts as thick and thin filaments slide over each other.
50 points
Name three nonspecific defense mechanisms
your body uses to protect itself from pathogens.10 points
Name three components that make up the second line of
non-specific immune response.20 points
What are antigens and antibodies?30 points
Explain cell mediated immunity.40 points
Explain humoral immunity. 50 points

CiliaStomach Acid
Sweat, Oil
10 points
Inflammatory responsePhagocytes (Neutrophils, Macrophages)
Complement – a group of Proteins Interferons – a group of Proteins
Natural Killer Cells
20 points
Antigens are the “bad guys” that infect you; your body recognizes them as foreignAntibodies are proteins made by Plasma cells, they attach to antigens and inactivate the antigens
30 points
A macrophage engulfs an antigen.Pieces of the antigen are placed on the surface of the macrophage. A helper T cell binds to the antigen. This binding activates the T cell which causes the cell to multiply and generate cytotoxic T cells.A cytotoxic T cell has receptors specific for the displayed antigen. They go and bind to infected cells with the antigen marker. Upon binding, molecules are released which kill the target cell that is infected.The cytotoxic T cells also generate Memory T cells and Suppressor T cells
40 points
A macrophage engulfs an antigen.Pieces of the antigen are placed on the surface of the macrophage. A helper T cell binds to the antigen. This binding activates the T cell which causes the cell to multiply.A B cell can then engulf an antigen; the activated Helper T cell binds to the B cell activating the B cell, which become memory B cells or Plasma cells that produce anitbodies.
50 points
Compare asexual and sexual reproduction.
10 points
Following fertilization, what are the 3 early embryonic stages in most
animals (not including 8-cell stage)?
20 points
What 3 layers eventually form in the gastrula?
30 points
What happens in Cleavage?
40 points
What do each of the 3 layers of the gastrula eventually develop into (ID 2 systems for
each layer)50 points
Asexual reproduction produces genetically Identical offspring to the parents (clones). Sexual reproduction produces genetically different offspring and leads to variation (requires 2 different gametes).
10 points
Zygote, blastula and gastrula
20 points
From outside in: ectoderm, mesoderm and endoderm
30 points
Cleavage is the rapid mitotic cell division of the zygote that occurs
immediately after fertilization.
40 points
Ectoderm – becomes the skin and the nervous system
Endoderm – will form the viscera including the lungs, livers, and digestive system.
Mesoderm – will give rise to the muscle, blood, and bones.
50 points
What are body symmetry that radiates from the center of an animal and 2-sided
symmetry?10 points
What is cephalization?
20 points
What is the longitudinal, flexible rod that runs along the dorsal axis of vertebrate
embryos, in the position that will become the vertebrate column?
30 points
Name 3 adaptations for evaporative heat loss by animals
40 points
ID a function of each of the 4 lobes of the cerebrum
50 points
Radial and Bilateral symmetry
10 points
A concentration of sensory equipment at the anterior end of an animal
20 points
A notochord
30 points
Sweating, panting, spraying water on the body
40 points
Frontal: language, speech, fine motor activities
