Across
- 3. the type of sweat glands found in the pubic region, breast and eyelids.
- 5. Golgi tendon organs respond to changes in ________.
- 7. Glutamate and aspartate are [excitatory/inhibitory] neurotransmitters (pick one option in the brackets)
- 10. this skin layer, also called the subcutaneous layer, insulates the body, acts as an energy reserve and anchors the skin to the underlying tissues.
- 12. These cells of the PNS provide myelination around axons.
- 13. The spinothalamic tract conveys ascending messages from the spine to the _______.
- 15. Post-ganglionic neurons of the sympathetic nervous system release this neurotransmitter.
- 16. The division of the autonomic nervous system that increases heart rate, mental alertness and and reduces digestive function when activated.
- 19. These sensory receptors monitor the position and movement of skeletal muscles and joints.
- 21. The central nervous system includes the spinal cord and the ________.
- 23. The brain region involved in emotions and fear conditioning.
- 24. This division of the autonomic nervous system triggers lacrimation, salivation and urination.
- 27. A single motor neuron and the muscle fibres it innervates.
- 28. Muscle spindles are comprised of [intrafusal/extrafusal] muscle fibres (pick one option in brackets).
- 30. The thalamus, hypothalamus and pineal gland are found in this brain region.
Down
- 1. The CNS is protected by 3 meninges, called the dura, arachnoid and _____.
- 2. The midbrain, pons and medulla oblongata are found in this brain region.
- 4. The brain region involved in memory formation.
- 6. Pre-ganglionic neurons of the sympathetic nervous system release this neurotransmitter.
- 8. the thinner of the 2 dermal layers.
- 9. Sensory neurons relay information to the _______ root of the spinal cord.
- 11. these sweat glands are found throughout the body, except on the nipples and genitalia.
- 14. these skin cells break down antigens (foreign substances).
- 16. this layer of the epidermis is only found in thick skin.
- 17. skin cells connect to each other through these structures.
- 18. This type of receptor mediates slow synaptic transmission (another term used to describe G protein-coupled receptors).
- 20. GABA and glycine are [excitatory/inhibitory] neurotransmitters (pick one option in the brackets).
- 22. The four brain lobes: parietal, occipital, temporal and _________.
- 23. These cells maintain the blood brain barrier.
- 25. the outermost layer of the epidermis.
- 26. these cells in the skin produce melanin which is responsible for protecting the skin from sun damage.
- 29. this skin layer contains blood vessels and deep connective tissue.
- 31. Efferent neurons are involved in motor responses, while _______ neurons convey messages to the CNS as part of the sensory system.
