Science term 1 nevous

Question 1

Homeostasis

Answer 1

the process of keeping the internal conditions of the body constant. This includes ph levels , blood glucose and body temperature

Question 2

Negative feedback

Answer 2

a case where outputs from a system are subsequently fed back into it, minimizing or reducing the effect of subsequent iterations

Question 3

Positive feedback

Answer 3

amplifying or magnifying the change or output

Question 4

Glucose

Answer 4

the main type of sugar in the blood and is the major source of energy for the body’s cells.

Question 5

Glucagon

Answer 5

a hormone that helps regulate blood sugar levels by stimulating the liver to convert stored glycogen into glucose when blood sugar levels are low.

Question 6

glycogen

Answer 6

form of stored glucose found in the liver and muscles, serving as a readily available energy source for the body.

Question 7

Insulin

Answer 7

helps blood sugar enter the body’s cells so it can be used for energy. Insulin also signals the liver to store blood sugar for later use.

Question 8

Neuron

Answer 8

Nerve cell. Functional unit of the nervous system which sends or receives signals.

Question 9

Axon

Answer 9

Part of the neuron that conducts impulses AWAY from the cell body

Question 10

Myelin sheath

Answer 10

covers the axon of some neurons and helps speed electrical impulses

Question 11

Dendrite

Answer 11

Part of the neuron that conducts impulses TOWARD the cell body

Question 12

Cytoplasm

Answer 12

holding the components of the cell and protects them from damage.

Question 13

Synapse

Answer 13

Gap between neurons

Question 14

Endotherm (Warm- Blooded)

Answer 14

Body heat regulation comes from INSIDE the animal and humans. Birds, humans and mammals, maintain a nearly constant internal temperature and do not change with the temperature of the environment.

Question 15

Ectotherm

Answer 15

Body heat depends on OUTSIDE of the animal. Animals, including fish, amphibians, and reptiles, and all invertebrates, which have an internal body temperature that changes with the temperature of the environment.

Question 16

Brain

Answer 16

Main control centre of the nervous system. controls voluntary and involuntary. This is surrounded by bone for protection

Question 17

Cerebrum

Answer 17

It’s about 80% of the brain and handles conscious, thoughts, emotion and store memories

Question 18

Cerebellum

Answer 18

A part of your brain that help coordinate and regulate a wide range of functions and in both your brain and body.

Question 19

What is the brainstem/ medulla

Answer 19

Structure that connects the cerebrum. Send message to the rest of your body to regulate balance, breathing, heart rate and etc.

Question 20

Sensory Neuron (body —> CNS)

Answer 20

Gather information about what is happening in and around your body.

Question 21

Detecting Stimuli

Answer 21

Sensory neuron are responsible for transmitting detected stimuli. Receptor specialised nervous tissue sensitive to a specific stimuli.

Question 22

Motor neurons (CNS —>Body)

Answer 22

Send impulse the brain and spinal cord

Question 23

Reacting to stimuli

Answer 23

Motor neuron allow the body to react to stimuli effector is the part of the body that respond muscle and glands.

Question 24

Central nervous system

Answer 24

The control centre that processes all the information it receives from the sensory neurons to decides whether it should make a response or not. This made of brain and spinal cord

Question 25

Brain

Answer 25

Main centre of the nervous system. Controlling both voluntary and involuntary. This is surrounded by bone (cranium) for protection.

Question 26

Cerebrum

Answer 26

80% of the brain that handles conscious, thoughts, emotion and store memories.

Question 27

Interneuron

Answer 27

receive signals from the peripheral nervous system, and efferent, or motor, neurons, which transmit signals from the brain
