Which of the following are NOT functions of the spinal cord?
maksim [4K]

Answer:

Reflexes are not a function of the spinal cord.

Explanation:

The spinal cord is part of the central nervous system and is made up of neurons that go along it (from the end of the brain stem almost to the bottom of the spine).

The spinal cord receives incoming messages from the peripheral nervous system (including the sensory neurons) and pass on messages from the brain to efferent neurons (motor neurons at muscles).

The spinal cord contributes to learning as it passes on the info received from sensory neurons (that there is an obstacle in the path) to the brain and passes on the response from the brain to the muscles (to lift the foot up higher).

The spinal cord is essential for integration as it passes on sensory information  to the brain to determine motor output.

Reflexes are when sensory information is quickly sent straight to motor neurons to move. It does not need to go to the brain (hence does not need to go to the spinal cord) for the reaction as it would be too slow. This is seen when someone who is paraplegic (paralysed at lower torso) can still move their leg in response to the doctor tapping their knee even when they cannot forcibly move their legs.

Therefore reflexes are not a function of the spinal cord.

What is the length of a triglycerides? How are glycerol and fatty acids “connected” to make a triglyceride?
Ostrovityanka [42]
Every fatty acids has a long hydrocarbon chain (with even amounts of carbons, usually 16 or 18) and a carboxyl group.

glycerol is a 3-carbon molecule with 3 -OH groups.

fatty accids and glycerol can be connected by single or double bonds, depending on if the fatty acid is saturated or unsaturated.

when a lipid forms, the -COOH functional groups of 3 fatty acids react with -OH groups of glycerol.

this leaves 16, 18, or 20 carbons, making a triglyceride 16, 18, or 20 carbons long.

hope this helps!
