Control and coordination (Unfinished, Only done till Coordination in Plants)

Bio aughhhh :rage... sonnn

Which receptors are responsible for taste?

• Gustatory receptors

Which receptors detect smell?

• Olfactory receptors

How does information pass from neuron to neuron? Explain with all steps

• Information is acquired at the Dendrite

• The recieved information sets off a chemical reaction at the dendrite

• The chemical reaction results in a electrical impulse

• The chemical impulse travels from the dendrite to the cell body, axon and finally reaches the nerve ending

• At the nerve ending the electrical impulse releases chemicals

• These chemicals cross the synapse and start a similar impulse in the dendrite of the next neuron

What is a reflex arc?

• A reflex arc is a neural pathway that controls a reflex action.

Where are reflex arcs formed at?

• Spinal cord

What are the two types of nerves present within the Peripheral nervous system?

• Cranial nerves

• Spinal Nerves

What does the Central Nervous System consist of?

• Brain

• Spinal Cord

What are the three major parts of the brain?

• Forebrain

• Mid Brain

• Hind Brain

What is the function of the forebrain?

• Main thinking part of the brain

• It has regions which recieve sensory impulses from various receptors

What is the function of the Mid Brain?

• The mid brain is responsible for processing sensory information and is involved in regulating motor control and reflexes.

Which components constitute the Hind Brain?

• Pons

• Medulla

• Cerebellum

What is the function of Pons?

• It controls facial expressions and regulates functions such as breathing and communication between different parts of the brain

What is the function of Medula?

• It controls the rate of respiration and it influences the rate at which the heart beats

What is the function of the Cerebellum?

• It maintains the posture and equilibrium of the body

What fluid surrounds the brain?

• Cerebrospinal Fluid

What is the function of the CSF?

• The Cerebrospinal fluid provides shock absorption

What protects the spinal cord?

• The vertebral column

How does a muscle cell move when they recieve a nerve impulse to do so?

• They change their shape so that they shorten

How do muscle cells change their shape?

• They have special proteins that change their shape in response to nerve impulses

• When this happens, new arrangements of these proteins give the muscle cell a shorter form
