How many parts are apart of the autonomic system?

2

How many different types of sensory receptors are there

5

What are the two parts of the motor division

Autonomic and somatic nervous system

The sympathetic and parasympathetic NS are specific divisions of the....

Autonomic nervous system

What might stimulate a response from the sympathetic nervous system? Explain

Being in a stressful or scary situation like running away from something dangerous because the sympathetic nervous system is what reacts to intense activities

Is a reflex apart of the PNS, CNS, or both? Explain

Both because

Sensory receptors

Cells that transmit info about changes in the internal and external environment

Stimuli

Changes that effect he body

Taste and smell receptors?

Chemoreceptors

Which receptors respond to chemicals?

Chemoreceptors

What are the 5 types of sensory receptors

Chemoreceptors, mechanoreceptors, pain receptors, photoreceptors, thermoreceptors

Gangilia

Clusters of cranial and spinal nerves

Some locations of photoreceptors

Eyes

What are things that the autonomic system controls?

Heart rate, sweating, breathing rate

Process of performing a voluntary action

Impulses from the brain are carried through the spinal cord where they synapse with dendrites of the motor neurons, The axons from these motor neurons extend from the spinal cord carrying impulses directly to the muscles causing the contractions that produce that voluntary action

Sympathetic NC process

Intense activity, fight or flight, speeds up heart rate, slows down digestion

What type of movement is under the autonomic system

Involuntary movement that is not under conclusion control

How might the autonomic system prepare your body for exercise

It's speeds up your heart rate and blood flow to your muscles, stimulates sweat glands, and slows down contraction of smooth muscles

Examples of using motor neurons under voluntary control

Lift a finger or wiggle your toes

Hearing and balance receptors?

Mechanoreceptors

Which receptors respond to touch and pressure?

Mechanoreceptors

Which type of sensory receptors most likely responds to a change in blood pressure that causes more force to be exerted on your look vessels?

Mechanoreceptors

Are brain impulses carried to motor neurons or muscles first?

Motor neurons

Some locations of chemoreceptors

Mouth, nose, blood vessels

Are their pain receptors in the brain?

No

Does the information go all the way to the brain during a reflex arc?

No

Reflexes are behaviors that....

Occur involuntarily without conscious control

What receptors are stimulated during a reflex arc?

Pain receptors

Which receptors respond to tissue injury?

Pain receptors

Vision receptors?

Photo receptors

Which receptors respond to the light stimuli?

Photoreceptors

Reflex arc

Rapid response due to pain receptors being stimulated

Parasympathetic NC process

Recovery, rest and digest, slow down heart rate and breathing, activates digestion

What are the two divisions of the peripheral nervous system?

Sensory and motor division

What are the parts that information passes by when being processed?

Sensory receptors Sensory neurons Spinal cord Brain Spinal cord Motor neurons Muscles and Glands

Touch receptor?

Sensory receptors for touch, temperature, and pain which are mechanoreceptors, pain receptors, and th

Process of reflex arc?

Sensory receptors react to stimulus and send an impulse to sensory neurons, Sensory neurons relay info to spinal cord, Interneurons in the spinal cord processes info and forms response, Motor neurons carry impulse to effector, The muscle or gland reacts

During a reflex arc what are the body parts that the information goes through?

Sensory receptors, sensory neurons, spinal cord, motor neuron, muscle

What is something that the somatic nervous system control?

Skeletal muscles

Some locations of mechanoreceptors

Skin, hair follicles, ears, ligaments, tendons

Some location of thermoreceptors

Skin, hypothalamus

What is the reflex arc apart of?

Somatic nervous system

Spinal nerves

Stimulate the rest of the body

What are the names of the two parts?

Sympathetic nervous system and parasympathetic nervous system

How do muscles and glands receive commands from the central nervous system?

The motor division of the PNS transmits impulses from the CNS to muscles or glands

How does the central nervous system receive sensory information

The sensory division of the peripheral nervous system transmits impulses from sense organs to the central nervous system

Suppose someone was playing baseball and trying to catch a pop fly ball. Explain how the different parts of the nervous system would respond.

The sensory nerves in the eyes spot the ball and send messages to the brain where information like height and distance are processed. Information travels through the motor neurons to the arms and legs so that the player can move to catch the ball

Which part of the PNS is apart of innate and learned behaviors? Why?

The somatic NS

Which receptors respond to temperature changes?

Thermoreceptors

What type is effects do these parts have on organs?

They have an opposite effect on organs they influence

Some locations of Pain receptors

Throughout the body

Sensory division

Transmits impulses directly from the sensory receptors the central nervous system

What type of movement is under the somatic nervous system

Voluntary movement under conscious control

Describe a situation where you would expect your sympathetic NS to be more active than your parasympathetic NS

When you fight because you are reacting to an intensive activity

Cranial nerves

Which nerves go through the openings in the skull and stimulate the head and neck?

Describe the advantage of a reflex response in the survival of an organism

a reflex response is very simple usually involving 3 neurons only and it is and very quick. this in terms of survival is very important because you can have an extremely rapid response to a certain danger or stressor
