    • What is the nervous system 

      The nervous system includes the brain, spinal cord and a complex network of nerves. This system sends messages back and forth between the brain and the body
    • what are the lobes of the brain decided the cerebrum in to different functions
      • the frontal lobe
      • the temporal lobe
      • the parietal lobe
      • the occipital lobe
    • what does the frontal lobe do
      it is the planning and engaging in goal directed behaviour, future consequences of current behaviour and choosing good and bad actions
    • what does the temporal lobe do
      it is the processes sensory input including auditory information, language and naming
    • what does the parietal lobe do
      it is the sensory, spatial processing and navigation
    • what do occipital lobes do
      it is the visual processing of the centre
    • what are the 4 reagions of the brain
      1. cerebrum
      2. diencephalon
      3. brain stem
      4. cerebellum
    • what is the fore brain
      it is the lambic system responsible for emotion, behaviour, motivation, long-term memory and olfaction
    • what is the forebrain made up of
      it is made up of the:
      • hypothalamus
      • amygdala: emotion centre of the brain
      • hippocampus: role of formation new memories about past experiences
      • thalamus: relay station for sensory information to where it can be processed
    • what is the consulate gyrus
      it plays a role in the reaction to pain and regulation of aggressive behaviour
    • what is the basal ganglia
      it is involved with the rule bases learning, choosing from potential actions working memory and attentions
    • what is the midbrain motorway
      • it is the pathway for nerve fibers to carry information from hearing and sight senses
      • the senses are not processed here
    • what is the midbrain
      it is responsible for: sleep, arousal, pain, consciousness and habituation
    • what are the midbrain’s neuron receptor
      it targets transmitters and drugs, including dopamine and serotonin receptors
      • the membrane receptor protein that is activated by a neurotransmitter
    • What does the mediate control
      Breathing, blood peressure and heart rate
    • What is the medulla oblongata
      • it extends from the hindbrain and merges into the spinal cord
      • It is responsible for breathing, blood pressure, heart rate
      • It is also allows for swallowing and coughing reflexes
    • How does the ventricular system protect the brain
      It is the interconnecting canals and cavities inside the brain, filled with cerebrospinal fluid
    • how do meninges protect the brain
      It is the protective layer around the brain made of connective tissue and collagen fibres
    • How does the blood-brain barrier protect the brain
      The membranes which control movement of substances
    • structure and function of the spinal cord
      F- the main function is to relay information about what happens inside and out side the body to and from the brain
      S- the spinal cord is protected by the spinal column made of vertebrea
    • What are the components of the eye
      • cornea
      • Lens
      • Optic nerve
      • Pupil
      • Macula
      • Retina
      • Iris
    • What is the cornea
      It is the transport dome at the front of the eye that bends light rays to help the eye focus
    • What is the lens
      It is a curved, transparent structure that reflects light rays onto the retina
    • What is the optic nerve
      It is a large sensory nerve that carries visual information from the retina to the brain
    • What is the pupil
      It is a hold in the centre of the iris that controls how much light enters the eye
    • What is the mascula
      It is a small sensitive area in the centre of the retina that provides central vision
    • What is the retina
      It is the inner, light sensitive layer of the eye where vision begins
    • What is the iris
      It is the coloured part of the eye found behind the anterior chamber
    • What is the function of the optic nerve
      It is the nerve fibres that connect the retina and the brain. The retina cells change sight into electrical impulses that the optic nerve sends to the brain( they are sent up side down)
    • What is the scerla
      It is the whites of the eye
    • What is the choroid
      It is a layer of blood vessels that line the back of the eye
    • What is the ciliary body
      It is found behind the iris and includes a ring shaped muckraker that changes the shape of the lens when the eye focuses
    • What is the medial and lateral Regis muscles medial rectus
      It moves the eye inwards or toward the nose and is also known as an adductor
