Unit 1
A formation of a dipeptide is what kind of chemical reaction?
Synthesis, Endergonic, Anabolic
What part of the hair is responsible for hair growth?
hair matrix
What are the bones the coronal suture unites?
Unites the frontal bone with the two parietal bones
Where is cerebrospinal fluid located?
Subarachnoid Space
What is a receptive field?
how much real estate, surface area is innervated by one particular sensory receptor
In Competitive Enzyme Inhibition
the inhibitor blocks substrate from binding at active site
What type of membrane is the Parietal Pleura?
Serous Membrane
What is the differences between the appendicular skeleton and the axial skeleton?
Axial: Bones not including limbs
Appendicular: bones of limbs & connections
Where are parasympathetic autonomic ganglia located?
Near or in the target organ
What is accomodation? What structure helps accomodate?
Ciliary Muscle
Differences of DNA and RNA
DNA- deoxyribose, double stranded, genetic material, A and T
RNA- ribose, single stranded, uracil instead of thymine, makes proteins
What junction anchors the microfilaments (part of the cytoskeleton) of one cell with the microfilaments of another cell
Adherens
What are the two main regulatory proteins in contraction that allow myosin to be binded to, when stimulated by calcium?
Troponin and Tropomyosin
What is the stretch reflex?
controls muscle length by causing contraction, preventing overstretching
What type of visual information does red, blue, and green cones transmit?
What are the monomers of proteins, nucleic acids, carbohydrates, and lipids
amino acids, nucleotides, monosaccarhides, lipids have no monomer
What is the difference between an exocrine and endocrine gland?
Exocrine glands have ducts, Endocrine glands are ductless
What remains the same length in a sarcomere?
A band, M line
This is the nerve that provides sensory info from the heart and abdominal organs
CN 10, Vagus
What are the 3 layers of the eyeball?
(outer layer) Fibrous Tunic, (middle layer) Vascular Tunic, Retina (Nervous Tunic) (inner layer)
Explain Noncompetitive Inhibition
Inhibitor binds to allosteric site, changing shape of active site so substrate cannot bind to enzyme
What systems work together to maintain homeostasis? Why?
Nervous and Endocrine
What are all the rotator cuff muscles?
Teres Minor, Subscapularis, Infraspinatus, Supraspinatus
Explain Saltatory vs Continuous Conduction
Continuous- slower, multiple channels
Saltatory- faster, less channels, myelin sheath
Auricle (Pinna), External Auditory Canal (Meatus), Tympanic Membrane (Eardrum) – Vibrates in response to sound waves. Ossicles, Malleus, Incus, Stapes, Oval Window, Cochlea, Organ of Corti (within the cochlea), Auditory (Cochlear) Nerve – Carries electrical impulses to the brain.
