Having a muscular physique
Having a heavy, rounded physique by large accumulations of fat
Having a thin, fragile physique characterized by little body fat
What are the levels of organization of the body (smallest to largest)
What is the smallest living unit of structure and function in the body?
What does the axial portion of the body consist of?
Head, neck, and torso
What are the three planes of the body?
Deals with the chemical makeup of living organisms and the underlying process of life
The number of protons +neutrons in the atom’s nucleus
A strong electrostatic force that binds the + and – charged ions together
Releases a hydrogen ion (H+)

An important function of the cell membrane
Maintain cell integrity
Peroxisomes contain enzymes that…
Detoxify harmful substances
Watery fluid in the cell
Main cell structures
Functions of plasma membrane
Self-identification, receptor site for messages, selective barrier
Projections from the cell that move material and mucus
DNA pairing to ATCG
Matrix of a tissue
The non-living intracellular material surrounding the cell of a tissue.
Basic characteristics of nervous system
Excitation and conduction
What is the most wide-spread and abundant tissue in the body?
Collect their secretory products at the apex/tip of the cell and release products by “pinching
off”. Causes some cytoplasm loss and damage but quickly repairs.
Collect their secretory products inside the cell and then rupture completely to release product. Cells self-destruct
Secrete their secretory products directly through the cell or plasma membrane. This is done without cell injury/loss of cytoplasm.
Hair usually found on fetus or newborn

Intramembranous and endochondral ossification
The 6 structural components of a typical long bone visable to the naked eye.
Diaphysis, epiphysis, articular cartilage, periosteum, medullary cavity, and endosteum
What are the main structures that form osteon?
Lamellae, lacunae, canaliculi, and haversian canals
What are the canals that connect blood vessels between adjacent, paralle osteons?
What are the tiny branches of hard bone present in calcellous bone?
