Anatomy 32 Quiz 2
| Question | Answer |
|---|---|
| Autonomic Nervous System (ANS) | Sensory input from the viscera and blood vessels, and motor output to involuntary effectors (Cardiac muscle, Smooth muscle, glands) |
| Axon | Single long process of a neuron that conducts nerve impulses away from the cell body. |
| Cortex | Thin, superficial layer of grey matter that covers the cerebrum and cerebellum |
| Dendrites | Highly branched processes neuron that carry impulses to the cell body (main receiving or input region. |
| Enteric Plexus | Network of neurons in the walls of the gastrointestinal (GI) track |
| Fasciculus (fasciculi:pl) | Axon bundles of nerve |
| Ganglion (ganglia: pl) | Cluster of cell bodies and the synaptic region for neurons located in the PNS |
| Gray Matter: | Contains cell bodies, dendrites, axon terminals of neurons, unmyelinated axons, and neuroglia. |
| Interneurons (association neurons) | Mulitipolar neurons located within the CNS that integrate incoming sensory information to elicit a motor response |
| Motor (efferent neurons) | Mulitpolar neurons, convey impulses from the CNS out through the PNS to effectors ("Involuntary" muscles or glands) |
| Nerve | Bundle of axons in the PNS |
| Nucleus | Cluster of cell bodies and the synaptic region for neurons located in the CNS |
| Neuroglia | Cells that support, nourish, and protect neurons |
| Neurons | Nervous tissue cells that are specialized for nerve impulse conduction |
| Parasympathetic Division | Division of the ANS that performs our housekeeping activities and conserves energy (rest and digest) |
| Perception | Our awareness of sensory input (Stimuli) |
| Sensory (afferent) Neurons | Unipolar (Pseudo-Unipoalr) neurons, convey stimuli impulses to the CNS for integration |
| Sensory Receptors | Monitor and transduce changes in our internal and external enviroment |
| Spinal Cord | Grey matter forms an H-shaped inner core surrounded by white matter |
| Soma | Cell body of neurons that contain the typical organelles plus chromatophilic (Nissl) bodies |
| Somantic Nervous System (SNS) | Sensory input from the head, body wall, limbs, and special sense organs and motor output to "voluntary" skeletal muscles |
| Sympathetic Division | Division of the ANS that activated under stressful situations ("fight or flight") |
| Tract | Bundle of axons in the CNS |
| White Matter | aggregates of myelinated axons |
