the diaphragm is innervated by the __________ nerve, which allows it to contract.

Answers

The diaphragm is innervated by the phrenic nerve, which allows it to contract.

What is phrenic nerve?  

The C3-C5 spinal nerves, which are parts of the cervical plexus, give rise to the phrenic nerve, a mixed nerve. It begins in the neck and travels through the thorax vertically before terminating on the diaphragm.

The phrenic nerve is bilateral, there are some significant distinctions between the left and right counterparts in terms of its courses and interactions with surrounding structures.

The primary purpose of the phrenic nerve, which makes it an essential part of the physiology of breathing, is to deliver the full motor innervation to the diaphragm.

Diaphragm is controlled by the phrenic nerve (the large dome-shaped muscle between abdominal and chest cavities). It is necessary for breathing. Diaphragm contracts as a result of signals sent by nerve (become thicker and flatter). This motion makes room for  lungs to expand and take in air (inhalation).

What do excitatory neurotransmitters cause?

Neurotransmitters might be either excitatory or inhibitory.

As the term suggests, excitatory neurotransmitters are in charge of exciting the postsynaptic cell.

Once the neurotransmitter is released from the presynaptic membrane, it travels through the synaptic space until it reaches the postsynaptic membrane.

When the molecule meets its receptor, it triggers a series of events that excite the receiving neuron increasing the action potential effects and allowing messages to be passed from one cell to the other.

Write a short description of the life cycle of a flowering plan

Answers

Answer:

Flowering plants begin as seeds. These seeds store energy and food within them long enough to reach the right environment and germinate. Germination is the development of a plant, growing from a seed into a seedling. Seedlings are the second stage of a flowering plant's life. This is when their roots begin to form and photosynthesis can begin. Next comes the growth period. After the seedling is planted, it requires a lot of food and energy as more leaves begin to emerge. The next stage of a flowering plant's life is the flowering stage itself. This is when buds and flowers begin to sprout. It enters the reproductive stage and pollination begins, allowing more seeds to be sown.

A red blood cell has been placed into three different solutions. One solution is isotonic to the cell, one solution is hypotonic to the cell, and one solution is hypertonic to the cell. Determine which type of solution is in each beaker based on the cell's reaction. Drag each item to the appropriate bin.

Answers

The type of solution in each beaker based on cell's reaction are :

Isotonic solution : Normal reactionHypotonic solution : The cell becomes turgidHypertonic solution : The cell becomes deformed

Matching each solution to the cell reaction

When the red blood cell is placed in an isotonic solution the solvent flows in and out of the blood cell at the same rate, when the cell is placed in a hypotonic solution the solvent flows into the cell at a faster rate causing the cell to swell ( becomes turgid ) also when the cell is placed in a hypertonic reaction the cell becomes deformed becomes it loses more water than it absorbs.
