What is the exocrine gland
Merocrine, apocrine and holocrine are secreted through?
|
What are sensory (afferent) and motor (efferent)
the PNS allows for communication between the CNS and the rest of the body via these two nerve fibers?
|
What is fibrocartilage
Row of thick collagen fibers..less firm than hyaline
|
What is the Nodes of Ranvier?
Myelinated axons conduct impluses faster than non myelinated axons, because action potentials can only occur here?
|
What is the diencephalon
Core of the forebrain where the thalamus and hypothalamus are located?
|
What is Loose CT
Adipose, areolar, and reticular are classified under this CT Proper?
|
What is the Na/K pump
Using ATP this system counters natural ion leakage and maintains resting potential by pushing 3__+ out and 2__+
|
What is smooth muscle tissue
This non-striated tissue is found in the walls of bladder blood vessels, respiratory, and digestive tracts?
|
What is refractory period?
Milliseconds in which membrane patch undergoing AP is insensitive to stimuli?
|
What is the mesencephalon
Including a pigmented nuclei, 2 cerebral pediuncles, two sets of superior and inferior colliculli (corpora quadrigemina) this section of the brainstem is known as the midbrain
|
What is skin
What organ is an biological, chemical and physical barrier that regulates temperature through sweat gland secretions and blood vessel dilation/contraction?
|
What is cytoskeleton
neurofilaments are shape-maintaining elements of?
|
What is stratum corneum
This layer of epidermis has 20-30 layers of dead cells that are highly keratinized and shed continuously?
|
What is cholinergic
ACh releases into cleft and bind to Na+ channels on post-synaptic neuron and triggers their opening at this synapse?
|
What is Cerebrospinal Fluid (CSF)
Free flowing through ventricles and circulating around the brain/spinal cord via subarachnoid space this fluid like substance nourishes the brain, carries chemical signals, and gives buoyancy to CNS organs?
|
What is stratum granulosum
3-5 layers of dying cells with deteriorating organelles; contains precursors to keratin and glycolipid waterproofers?
|
What are chemically-gated, leak and voltage-gated
These three channels govern ion impermeability?
|
What is papillary layer
The superficial layer of dermis with peg-like papillae that contribute to fingerprints?
|
What is temporal
When presynaptic neurons transmit AP through rapid succession this is known as __________ summation
|
What is the abducens nerve (VI)
This cranial nerve originates at the pons and innervates lateral rectus muscle for side-to-side eye movement?
|
What is serous
These membranes line pleural pericardial and peritoneal cavities?
|
What are Oligodendrocytes (CNS) and Schwann cells (PNS)
While this supporting cell forms myelin sheath on the axons in the CNS, another supporting cell forms on larger nerve fibers in the PNS?
|
What is merocrine?
This coiled, tubular sweat gland produces 99% H2O + NaCl + lactic acid that cools the body
|
What is -60mv
Threshold for AP generation can be determined at this voltage meter reading?
|
What is dural folds
Falx cerebelli and Tentorium cerebelli are two of three _______ that limit free movement of the brain.
