The Nervous System

QuestionAnswer
What is the nervous system responsible for ? all internal communication and coordination
What is the nervous systems primary role ? (homestasis) to maintain a constant balance of the internal environment, known as "homeostasis"
Describe Homeostasis (Nervous System) the constant balance of the internal environment
If every nerve end in the human body was placed end to end how far would it stretch 2.5 times around the world !!
"homeostasis" is achieved with the help of the brain and a huge complex network of what other 2 things that run throughout the body ? electrical nerves & chemical messages
summing up the role of the nervous system its role its to gather info (S), analyse the gathered info (I) & and (R)espond to the received info - define "SIR" (S)ENSATION - (I)NTERGRATION - (R)ESPONSE
explain the nervous system function SENSATION'S role in gathering info, sensors in the body gather info about the external or internal environment
relaying infor to the brain when a body part is moving or its position relative to the rest of the body is the role of ? IP internal proprioceptors
what are proprioceptors and where are they found Sensory receptors located in themuscles, tendons, joints & inner ear
Name the nervous system function SENSATION'S "external" sensors & example Eyes, Ears, Mouth - air temp or space available
What can the nervous system function SENSATION'S "internal" sensors proprioceptors detect carbon dioxide levels in blood
explain the nervous system function INTEGRATION'S (interpretation/anaysis) role on gathered info via the sensation function. interprets & analyses the info from the sensors "decides" on the appropriate action.
What 2 actions are available to the nervous system function INTEGRATION ? "Voluntary" - eg Muscle movement // "Involuntary" eg digestion
explain the nervous system function RESPONSE'S role on the analysed info gathered via the integration function the analysed info now initiates an appropriate reaction
Give an example of a reaction initiated by the nervous systems function RESPONSE A muscle contraction to lift a weight, perform a movement or glandular secretions
What system does the nervous system work closely with ? (E) ENDOCRINE system
What is the "endocrine" system responsible for so "homeostasis" can be maintained ? the release of hormones (chemicals)
What two primary divisions make up the nervous system ? CNS & PNS CENTRAL & PERIPHERAL Nervous systems
What nervous system division is know as the control base for the whole nervous system ? the CNS
What parts of the body is the CNS comprised of ? The brain & the spinal cord
All nerve impulses that stimulate muscles to contract & create movement of the body originate from which primary nervous system ? CNS
Which primary nervous system consists of all the branches of nerves that lie outside the spinal cord ? PNS
What is the role of the PNS (peripheral nervous system) To carry messages through its network of nerve cells to & from the CNS
what two systems does the PNS subdivide into ? (S/A) The SOMATIC & AUTONOMIC systems
Which subdivision of the PNS controls voluntary(conscious) movement of the skeletal muscles ? The SOMATIC eg for walking, lifting weights etc
Which subdivision of the PNS controls involuntary movement (without conscious) functions ? the AUTONOMIC system eg digestion & heart rate etc
Whats Happening !! would apply to which nervous system function (SIR) SENSATION
What does it mean !! would apply to which nervous system function (SIR) INTERGRATION
What am I going to do about it !! would apply to which nervous system function (SIR) RESPONSE
Name the four parts (aspects) of the brain CEREBRUM - DIENCEPHALON - BRAIN STEM - CEREBELLUM
which part of the brain is the largest, most superior aspect & takes up most of the skull ? CEREBRUM
Which aspect of the brain consists of the thalamus & hyperthalamus ? DIENCEPHALON
Which is the smaller aspect of the brain ? CEREBELLUM
which aspect of the brain stores all learnt skills & controls the groups action of muscles ? CEREBELLUM
which two aspects of the brain communicate work in harmony ? CEREBRUM & CEREBELLUM
which part of the brain consists of the medulla oblangata, mid brain & pons ? BRAIN STEM
which part of the brain is the continuation of the spinal cord ? BRAIN STEM
which part of the brain is the inferior aspect ? BRAIN STEM
what 4 segments (vertabrae) does the spinal cord consist of ? Cervical, thoracic, lumbar & sacral
what organ & nervous system is the spinal cord the communication link for brain & PNS
the spinal cord intergrates incoming info & produces responses via reflex mechanisms, what is this know as ? reflex arc
What are nerve cells know as ? Neurons
Neurons (nerve cells) are responsible for transmitting what kind of messages ? Electrical
spinal are nerves are divided into what two types of neuron ? (M&S) Motor & Sensory
Which neurons carry messages "to" the CNS ? Sensory - from the sensory organs
Which neurons carry messages "from" the CNS ? Motor
Which Neurons arrive on the posterior side of the spinal cord ? Sensory
Which Neurons transmit nerve impulses to muscles & glands ? Motor
Which Neurons exit on the anterior side of the spinal cord ? Motor
Which part of a neuron stores the cells genetic info eg DNA ? Nucleus
Which part of a neuron directs the activities of the neuron The Cell body
which part of a neuron picks up impulses & sends them to the cell body ? Dendrite
Which part of a neuron transmits messages away from the cell body Axon
Which part of a neuron insulates the AXON to speed up message transportation ? Myelin (Sheath)
Nucleus, Cell body Dendrite, Axon, Myelin & Nerve ending all are parts of ? A neuron
What organ has over 100 billion neurons The brain
How many neurons does the body contain ? Millions
where do motor neurons transmit nerve impulses to, to create movement muscles
Which nervous system is responsible for the ‘fight or flight’ response that speeds up the heart rate Sympathetic
