Intro to Human Body
What is the study of the functions of living cells?
Physiology
An ion with a negative charge is called:
Anion
This type of solution contains a higher concentration of solutes compared to the fluid within the cell
Hypertonic
This type of tissue lacks blood vessels and must depend on a basement membrane for nutrients
Epithelial tissue
This type of skin cancer is the most deadly because it quickly metastasizes
Malignant melanoma
Name the two major body cavities.
Doral and Ventral
How is the atomic weight of an atom determined
By the number of protons and neutrons
In which phase of mitosis do the chromosomes line up along the center of the cell
Metaphase
Consists of a single layer of flat, scale like cells.
Simple Squamous Tissue
Bone cells that dissolve unwanted or unhealthy bone are called
Osteoclasts
Term the describes the abdominal region just beneath the breastbone
Hypochondriac region
A compound that dissociates in water to create a solution capable of producing an electrical charge is called
Electrolyte
A form of vesicular transport that releases substances outside the cell is called
Exocytosis
This membrane surrounds each lung and lines the thoracic cavity
Pleura
What structure in the dermis causes hair to “stand on end
Arrector pili muscle
The process of homeostatic regulation operates most often through a system of?
Negative feedback
What is the name of the chemical process used to break down complex compounds into simplistic ones to release energy
Catabolism
Describe the sodium-potassium pump steps
Pump uses energy in the form ATP to transfer sodium from inside the cell funnel into receptor sites on channel protein. ( Sodium BINDS).
ATP causes the channel protein to release sodium ions into a extracellular fluid( moving from lower to higher concertation Chemical Caused)
Two potassium ions from outside cell enters the same channel protein. (shape change to allow potassium to bond)
Potassium ions are released inside cell. (keeps potassium concentration higher and sodium lower in cell
Name two types of connective tissue
Loose Fibrous, Dense fibrous, Cartilage, bone, and blood
Describe the steps of muscle contraction beginning at the neuromuscular junction
Nerve impulse → Acetylcholine release → Action potential in muscle fiber → Calcium release from sarcoplasmic reticulum → Actin-myosin cross-bridge → Contraction
Body System Consists of skin, hair, and nails
Integumentary
Ionic bonds are formed when
one atom transfers an electron from its outer shell to another atom
These cellular structures are hair like processes along the surface of a cell that beat in waves
Cilia
A Tissue that's a continuous sheet of tightly packed cells and covers the body surface, lines body cavities, and organs and forms certain gland
Epithelial Tissue
Which type of joint is also known as diarthroses,
Freely movable joint (synovial)
