Science Questions Flashcards
Which cells excrete pepsinogen?
chief cells of the stomach
Which organ is responsible for a majority of digestion?
Small intestine
Sensory neurons
Carry an afferent impulse- to the brain
Contraction occurs when
Thin actin filaments slide past thicker myosin filaments causing the sarcomere unit to shorten
Which nerve structure transmits impulses to other cells?
Axon
Inflammation
Innate immune response resulting in redness, swelling, heat, and pain.
The endocrine system produces what response?
Slow initiating, prolonged response on other body systems
What is the integration center between endocrine and nervous system?
Hypothalamus
Exocrine glands
Release chemicals to outside the body or to another surface within the body
Endocrine glands
Releases chemical substances directly into the bloodstream or tissues of the body
What gland has an exocrine function and aids in blood glucose regulation?
Pancreas
Epidermis
Outer layer of the skin made of epithelial tissue
Dermis
Middle layer of skin made of connective tissue
Hypodermis
Lowest layer of skin
Osteoclast
Bone cells that perform calcium mineral reabsorption
Osteoblasts
Synthesize bones, the secretions allow for mineralization
Osteocytes
Star shaped bone cell. Maintains structure. Senses physical stress.
Osteons
Cylindrical structures comprised of compact bone tissue that surround the haversian canal
Yellow marrow is located in?
Long adult bones in the Medullary cavity
Spongy bone
Fewer osteons than compact bone, where red bone is formed.
B-cells
Lymphocytes that make antibodies in response to antigens.
Helper T cells
Secrete interlukens that trigger the action of other cells.
Cytotoxin T cell
Attacks foreign cells, activated by interlukens
Macrophage
Large white blood cells that ingest foreign materials
Blastophil
Releases histamine
Median/Sagittal/Midsagittal plane
Plane that passes through the middle of the body separating the left and right
Parasagittal plane
A plane parallel to the Sagittal plane
Transverse plane
Located at midsection, separates superior and inferior sections
Coronal plane
Separates the anterior and posterior sections
Ribosomes
Facilitate protein synthesis in the rough endoplasmic reticulum
Emphysema
Increased residual volume due to decreased elasticity
Immunoglobulin
Antibody
Interferon
Protein secreted by leukocytes when they are infected with viruses
Lutenizing hormone
Controls production of testosterone
Gametes
Sperm
Proximal convoluted tube
First locations where glucose and other substances are reabsorbed into the blood
Glomerulus
Capillaries where blood pressure pushes water, salt, glucose, amino acids, and urea from the blood.
Bowmans capsule
Cup shaped structure that surrounds and collects filtrate from the glomerulus
Renal pelvis
center of the kidney where urine collects before moving to the ureter
Mendel’s law of segregation
His first law of inheritance, each gamete carries only one allele for each gene
Amino acids
monomer of protein
Nucleotides
The monomer of DNA, one type of nucleic acid
Dependent variable
variable being measured in an experiment, effect
Motor neurons
Carry efferent impulse- from the brain
