2. Lacks hair
3. Very thick epidermis
300
In the Golgi Apparatus, the proteins are not only sorted and their carbohydrates trimmed, but they obtain their ____________ structure.
Quaternary
300
When the Action Potential's depolarization opens the Voltage-gated Calcium Channels in the Axon Terminal, the influx of calcium triggers the release of neurotransmitters into the synapse via this type of membrane transport.
Exocytosis
400
The antecubital region is _______ to the Olecranal region.
Ventral or Anterior
400
The two molecules are held together by a(n):
Hydrogen (H+) bond
400
These structures provide space for capillaries and nervous system structures to encounter the epidermis, and create friction ridges in the thick skin.
Dermal papillae
400
Molecular motors carry transport vesicles down "train tracks" made of this type of cytoskeleton fiber.
Microtubule
400
When a stimulus is strong enough to depolarize the local area of the cell to the threshold voltage of -55mV, these channels open, triggering an Action Potential.
Voltage-Gated Na+ Channels
500

Eccrine or Merocrine Sweat Gland
500
This organelle synthesizes lipids and glycogen, and breaks down toxins.
Smooth Endoplasmic Reticulum
500
The sluggish closing of the Voltage-gated K+ channels causes the cell to become ________________, making it relatively difficult for the cell to reach threshold for a brief time.
Hyperpolarized
