3. What is a myofibril? Longitudinal striations in the muscle form transverse striations in the muscle.
4. Sketch a picture of a sarcomere. Label the I-band, the A-band, the Z line and the H-zone.

Organization of the human Body system
Explain the difference between anatomy and physiology. Anatomy is the study of the structure of the body parts. Physiology is the study of the function of the function of the body
Please organize the following structures in order from smallest too largest: system, tissue, organ, and cell. Atom, molecules, organelles, cells, tissue, and organ system
In the term physiology the suffix -logy means what?
What is the type of membrane that lines all of the passages leading the exterior? Mucous membrane
What do you call a mass of cells that all perform the same function? Organs
What type of tissue is specialized for the conduction of nerve impulses?
The term epidermis contains a prefix and a root term. What is the root in this word and what does it mean? What is the prefix in this word and what does it mean? The epidermis is the epithelial sheets of the cutanous membrane
The term cavity appears frequently in this lesson. What does it mean? A whole
Name the four main types of tissue and describe their function. Epithelial, Connective, Muscle, and Nerve
A cell is made of __Cytoplasm except for the nucleus, which is made of ___Proton and neutrons.
What type of membrane lines joint cavities and outer surfaces of bones? Fibrous membrane
What is an organ system? Masses of cells which are specialized for certain function from the basic tissues of the body
Name the five types of membranes and where each is located. Cutaneous, Mucous, Serous, Fibrous, and Fasica
What is the function of the cell membrane? The nucleus? Layer of epithelial and connective tissue from a membrane3
The cutaneous membrane is made of two distinct layers. Name each of these layers and describe what they are made of. Protection- covers the entire body, acts as an antibacterial layer. Also protects the skin from drying and injury. Heat Regulation- helps retain body heat as well as losing body heat through perspiration thus cooling the body

Study question in Anatomy Text
Chapter 2 14-15
Distinguish between the study of anatomy and the study of Physiology. Anatomy is the study of the structure of the body parts. Physiology is the function of the body parts.
Give an example that shows the relationship between the structure and function of the body parts. Stomach because its hollow and food have to go through
List the levels of the organization within the human body in reference to specific organs. Atom, molecules, macromolecules, organelles, tissue, organ, organ system.
Distinguish between a midsagittal cut, a transverse cut, and a frontal cut. Midsagittal (vertical), Transverse ( horizontal), Frontal (corneal)
Distinguish between the dorsal and ventral body cavities, and name two smaller cavities that occur within each. Dorsal is the back and ventral is the front. The two smallest are cranial cavity and spinal cavity.
10. Define homeostasis, and explain its importance. Homeostasis means that are the human body internal environment remain relatively constant, regardless of the condition in the external environment
Objective question part IV and part V
Digestive system- stomach
Urinary system- kidneys
Respiratory system - lungs
Circulatory system - Heart
Reproductive system - ovaries
Nervous system- brain

Objective Question
1.Packing and secretion- golgi apparatus
2. Cell division- centriole
3. Powerhouse of the cell- Mitochondria
4. Protein synthesis- Rough ER
