Microscopic Muscle Anatomy
This band in the sarcomere contains only thin filaments.
What is the I Band?
This type of contraction generates tension with no change in length of the muscle.
What is an isometric contraction?
This structure of the neuron brings an impulse from the cell body to the synapse.
What is an axon?
This spinal nerve exits below the T9 vertebrae
What is spinal nerve T9?
This is the structure that connects the right and left hemispheres of the brain.
What is the corpus callosum?
The process that occurs when myosin heads change shape to shorten the sarcomere.
What is the power stroke?
These three connective tissue layers all merge to from a tendon.
What are epimysium, perimysium, and endomysium?
These are the parts of the CNS that contain myelinated neurons.
What is white matter?
This is the portion of the spinal cord where it terminates around L1.
What is the conus medullaris?
This structure is the primary relay station of the brain.
What is the thalamus?
This is the regulatory molecule that covers the myosin-binding site on actin.
What is troponin?
Biceps brachii and brachioradialis perform this motion.
What is elbow flexion?
These are gaps between myelin that allow for faster impulse transmission.
What are the nodes of Ravier?
This is the mass of cell bodies found lateral to the spinal cord that brings in sensory information.
What is the posterior root ganglion?
These are the 5 lobes of the brain.
What are the frontal, parietal, occipital, temporal, and insula?
This band of the sarcomere never changes shape during contraction.
What is the A band?
This abdominal muscle has fibers running superomedially.
What are the internal abdominal obliques?
These are the 5 components of a reflex arc.
What is a receptor, sensory neuron, interneuron, motor neuron, and effector?
This mixed cranial nerve innervates all visceral organs, like the GI tract and kidneys.
What is the Vagus nerve?
These structures connect the cerebellum to each segment of the brain stem.
What are the peduncles?
This molecule must bind to the myosin head in order for the cross-bridge to release and the muscle to relax.
What is ATP?
These muscles make up the rotator cuff.
What are subscapularis, supraspinatus, infraspinatus, and teres minor?
These are the 6 types of glial cells.
What are Schwann's cells, satellite cells, oligodendrocytes, ependymal cells, astrocytes, and microglial cells?
What are the Oculomotor, Abducens, and Trochlear nerves?
This organ in the diencephalon regulates the connection between scents and emotional responses.
What is the Habenular nuclei?
