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
