-
Ectomorph somatotype
Having a thin, fragile physique characterized by little body fat
-

- System,
- Organism
-
What is the smallest living unit of structure and function in the body?
Cells
-
What does the axial portion of the body consist of?
Head, neck, and torso
-
What are the three planes of the body?
- Sagital,
- Transverse,
- Cornal
-
Deals with the chemical makeup of living organisms and the underlying process of life
Biochemistry
-
Atomic Weight
The number of protons +neutrons in the atom’s nucleus
-
Ionic Bond
A strong electrostatic force that binds the + and – charged ions together
-
Acid solution
Releases a hydrogen ion (H+)
-
Base solution
Accepts hydrogen ions (OH-)
-
pH scale
- below 7 is more acidic
- above 7 is more alkaline (base)
-
An important function of the cell membrane
Maintain cell integrity
-
Peroxisomes contain enzymes that…
Detoxify harmful substances
-
Cytosol
Watery fluid in the cell
-
Main cell structures
- Organelles,
- Plasma membrane,
- Cytoplasm
-
Functions of plasma membrane
Self-identification, receptor site for messages, selective barrier
-
Cilia
Projections from the cell that move material and mucus
-
-
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?
Connective
-
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.
Apocrine glands
-
Collect their secretory products inside the cell and then rupture completely to release product. Cells self-destruct
Holocaine glands
-
Secrete their secretory products directly through the cell or plasma membrane. This is done without cell injury/loss of cytoplasm.
Merocrine glands
-
Lanugo
Hair usually found on fetus or newborn
-
Three major types of bone cells
Osteoblasts, osteoclasts, and osteocytes.
-
What are the 5 funtions of bone?
Support,protection, movement, mineral storage, and hematopoiesis
-
What are the two types of bone formation?
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?
Volkmann canals
-
What are the tiny branches of hard bone present in calcellous bone?
Trabeculea
