What are organelles? Name three examples
"Little organs" within the cell that perform specific functions. Examples include Endoplasmic reticulum, Golgi Apparatus, Mitochondria, Lysosomes, Centrosomes, Cytoskeleton, Cilia and Flagella, and Nucleus.
100
What are the four major types of tissue?
Epithelial, Connective, Muscle, Nervous
100
What does your pectoral girdle consist of?
Shoulders, upper and lowers arms, wrist, palm of the hand, and fingers
100
What are the types of muscle tissue?
Skeletal, Smooth, Cardia
100
List the parts in which information passes in neurons.
Cell body, Dendrites, Axons
200
What is selective permeability?
What regulates what enters and leaves the cell.
200
What's the difference between tendons and ligaments?
Tendons are muscles to bones, meanwhile ligaments are bones to bones.
200
What are the functions of the bone?
- support and protection
- body movement
- blood cell formation = hematopoiesis
- storage of inorganic materials (calcium, magnesium, sodium, potassium)
200
What's the difference between Myosin and Actin?
Myosin- thick filaments (A bands= dark)
Actin- thin filaments (I bands= light)
200
What are neurons?
Masses of nerve cells that transmit information function unit the nervous system.
300
Name and list the phases of mitosis within a cell.
Prophase -> Metaphase -> Ananphase -> Telophase
Note: Interphase is a part of the cell cycle, but mitosis starts at prophase.
300
What type of tissue is affected in epidermolysis bullosa?
Connective Tissue
300
What are three parts of the long bone structure?
Epiphysis, Diaphysis, Articular cartilage, Periosteum, and Medulla
300
Where does a nerve and muscle fiber come together.
Neuromuscular junction
300
Locate the 4 lobes of the brain that make up the cerebrum.
400
Name one example of active transport and one example of passive transport.
Active: exocytosis, endocytosis
Passive: diffusion, osmosis
400
What is the role of dendrites in nerve tissue?
Receives messages from other neurons
400
Osteocytes are...
Mature bone cells that are enclosed in tony chambers called lacunae, which form rings called lamellae around a haversian canal that houses blood vessels. Osteocytes are connected by canaliculi.
400
Describe muscle dystrophy.
A disorder causing muscle weakness and leads to reduce mobility.
400
Function of the nervous system.
Coordinate the body's systems by receiving and sending information; maintaining homeostasis.
500
Molecules move in what direction?
From areas of high concentration to areas of low concentration.
500
What is the muscle tissue like in the skeletal?
Located in the skeletal muscles, voluntary, striated
500
Locate the sutures of the skull.
500
What is the sliding filament theory?
The theory of how muscle contracts is the sliding filament theory. The contraction of a muscle occurs as the thin filament slide past the thick filaments.
500
Name one neuroglial cell and list their function.
Microglial cells: Immune function; digest debris, kills bacteria.
Oligodendrocytes: Make myelin sheath that provides insulation around the axons
Astrocytes: Connect blood vessels to neurons
Ependymal Cells: Forms membranes around tissue
Schwann cells: form the insulating myelin sheath around the neurons in the PNS
