Map 6 (Senses (Simulus type (Thermoreceptor (Cold sensitive receptors,…

- - - - Located on the roof of the nasal cavity
      - Made of...
        
        Olfactory sensory neurons
        
        Pseudostratified columnar epithelium
    - - Olfactory receptors
        
        Olfactory sensory neurons
        
        Olfactory tract
        
        Limbic system (emotional brain)
        
        Primary olfactory cortex (in temporal lobe)
  - - - Located in the tongue, cheek, posterior wall of pharynx and epiglottis.
      - Made of gustatory epithelial cells
    - - Cranial nerves
        
        Medulla oblongata
        
        Thalamus
        
        Gustatory cortex in the insula
  - - - Sclera
        
        White part of eye
        
        Made of dense irregular connective tissue
        
        Protective and gives shape
      - Cornea
        
        Clear
        
        Focuses light onto retina
        
        Allows light into eye
    - - Choroid
        
        Nourishes other layers
        
        Deeply pigmented
        
        Prevents light from scattering
        
        Makes vision clearer
    - - Retina
        
        Photoreceptor
        
        Axon coverage form the optic nerve
  - - - Auditory occicles
        
        Malleus, incus and stapes
      - Tympanic membrane

        Medulla oblongata
        
        Pons
        
        Midbrain
        
        Thalamus
        
        Primary auditory cortex (in temporal lobe)
  - - - Cold sensitive receptors
      - Warm sensitive receptors
    - - Sensitive to light
    - - Sensitive to chemicals
      - Air, saliva, and blood
    - - Pain and danger type stimulus
    - - Sensitive to touch
      - Pressure, vibration and stretch
        
        Barereceptor
        
        measures blood pressure
        
        Changes tension on arterial wall
  - - - Stimulus comes from environment
      - Located in our skin and special senses
    - - Stimulus comes from internal organs
    - - Stimulus comes from our muscles
      - Includes tendons, ligaments and joints
      - Proprio = own
- - - - Brain and spinal cord
    - - Receives and processes incoming signals and responds to them
  - - - Cranial nerves attached to the brain
      - Spinal nerves attached to spinal cord
    - - Be sensitive to stimuli and to send information towards the CNS
  - - - Output to skeletal muscle
    - - Input from skin, skeletal muscle, joints and limbs
  - - - Mainly from the ventral body cavity
      - Smooth muscle
      - In respiratory, urinary, digestive and reproductive systems
      - Arrector pili
      - Sweat glands
    - - Input from ventral body cavities
- - - - always multipolar
      - cell bodies in the CNS travel to PNS then to glands and muscles
    - - unipolar or bipolar in special senses
      - located in the ganglia
    - - between neurons in CNS
      - 99.98% of all neurons
      - structurally multipolar
- - - - Supports neuron
      - Helps maintain chemical environment
      - Found in white matter
    - - Remove microbes and damaged nerve tissue
      - Located throughout brain and spinal cord
    - - Located in the canal of the spinal cord
      - Line spaces that are filled with cerebrospinal fluid
    - - Structurally supportive
      - Monitors material exchanges
  - - - Part of the nerve that carries a signal
    - - Bundle of axons
    - - Fibrous connective tissue that surrounds the nerve
    - - A single nerve cell
    - - Insulation
