Nerves
Nerves are thread-like structures that form a network of pathways that transmit information from the brain to the body and the body to the brain, in the form of electrical impulses.

What channels are open during depolarization and during repolarization?
During depolarization Na channels are open
During repolarization K channels are open
Do you still have a stretch reflex with a cervical nerve injury?
Yes, you may still have a stretch reflex with a cervical nerve injury.
What is meant by summation at a synapse and how can the two ways it is accomplished be described?
Summation is the method in which signal transmission between neurons occurs. Summation occurs through excitatory neurotramitters and inhibitory neurotransmitters. Excitatory produces depolarization of the postsynaptic cell. Inhibitory mitigates the effects of an excutatory neurotransmitter.

What are nerve endings of the sense of taste commonly called?
"Taste buds" is the common name for the nerve endings for the sense of taste.
What happens to chromosomes during synapse?
During synapsis, which occurs in prophase I of meiosis, homologous chromosomes pair closely together to form a structure called a tetrad. This process allows for genetic recombination through crossing over, where segments of DNA are exchanged between non-sister chromatids. This exchange increases genetic diversity in the resulting gametes. Ultimately, synapsis ensures proper alignment and segregation of chromosomes during meiosis.
A synapse is a small gap at the end of a neuron that allows information to pass from one neuron to the next.
Which cranial nerve supplies the thumb?
It is not one of the cranial nerves (I-XII), it is cervical nerve number 6.
Can vegus nerve disorder be cured by medicines?
Vagus Nerve disorder cannot so much be cured as it can be treated by medicines with positive effects. Medicines may be prescribed for short or long term use. Other treatments include exercises and surgery.
How many cannabinoid receptors in the human body?
The endocannabinoid system is a ubiquitous lipid signaling system that appeared early in evolution and has important regulatory functions throughout the body in all vertebrates. It consists of a family of G-protein-coupled receptors, the cannabinoid receptors (CB1 found in the brain and many peripheral tissues, and CB2, primarily found in immune cells); endoligands to activate these receptors; and two enzymes, the fatty acid amide hydrolase and the monoacylglycerol lipase, to metabolize the endoligands. The endoligands of the cannabinoid receptor system, small molecules derived from arachidonic acid, are called endocannabinoids.
The main endocannabinoids, anandamide (arachidonoylethanolamide) and 2-arachidonoylglycerol, bind primarily to CB1 and CB2 receptors, but also to the vanilloid receptor producing a wide diversity of effects since they function as agonists, antagonists and partial antagonists. (Cannabinoids function as antagonists to the vanilloid receptor, a.k.a. the capsaicin receptor, since it can be activated by capsaicin and is involved in the transmission and modulation of pain.)

Where is the patella nerve located?
The saphenous nerve (which will become the patellar nerve) is a purely sensory nerve that crosses below the knee from medial to lateral and innervates the skin below the patella.
