Release of a neurotransmitter across the synapse is triggered by the entry of Ca++ into the presynaptic axon. No Ca++ entry means no transmission across the synapse.

Answer:

If the calcium ion channels in the axon terminal were blocked, then no synaptic transmission occurs.

Explanation:

The synapse has 2 parts one is post synaptic cleft and other is pre synaptic cleft. The pre synaptic cleft contains synaptic vesicles which  have neurotransmitters. These neurotransmitters are in the inactive form.

When the calcium ion is coming and bind with the vesicle, the neurotransmitter gets activated. Then the vesicle binds with another protein and releases the neurotransmitter to the post synaptic vesicle. Thus information goes from pre synaptic cleft to post synaptic cleft and synaptic transmission occurs.

If the calcium ion channel is blocked, no calcium ions come into the axon terminal, the neurotransmitter can't active and no synaptic transmission happens.

NemiM [27]

Answer:

a tumor is a growth of abnormal cells in the brain tissue, in this case they are malignant cancer cells since their growth is very fast, some are primary that start directly in the brain and other metastatic that start in another part of the body, in the case of Mister AH always had primary symptoms.

Tumors in the brain can show various symptoms. These are some of the most common:

Headaches, usually in the morning

Nausea and vomiting

Changes in the ability to speak, hear or see

Balance or walking problems

Problems with thinking or memory

Weakness or longing to sleep

Changes in mood or behavior

Seizures

tumors can destroy brain cells which can cause inflammation and damage to parts of the body depending on where in the brain this is exerted, this also aggravates the symptoms.

Radiation therapy used to treat brain cancers increases the risk of brain tumors up to 20 to 30 years later.

In this case, he was causing this same reaction to Mr. AH, which may also have another type of tumor such as

Meningiomas and schwanomas are two other types of brain tumor. These tumors:

They occur in most cases between the ages of 40 and 70.

They are not usually cancerous, but they can still cause serious complications and death due to their size or location. Some are cancerous and aggressive.
