CNS pt2
Descending tracts of the CNS contain axons carrying these signals
What are motor commands
Sensory information from the visceral organs is carried through this cranial nerve. This nerve is also the only one to leave the cervical and cephalic regions
What is the phrenic nerve
Increased heart rate, dilation of the pupils, and glucose release are all effects of this division of the autonomic nervous system
What is the sympathetic division
This type of tissue functions to transmit and process information
What is nervous tissue
The glenohumeral joint is highly flexible but also unstable and can get dislocated frequently. This joint would be categorized under this name
What is ball-in-socket joint
This expansion of the spinal cord supplies nerves to the lower extremities
What is the lumbar enlargement
The olfactory, visceral and gustatory receptors fall under this larger class of receptors that monitor extracellular fluids.
What are chemoreceptors
What is norepinephrine
This type of epithelial tissue functions to propel mucus across a cell surface and may be found in locations such as the larynx
What is ciliated pseudostratified columnar epithelium
Supination is the opposite to this articulation
What is pronation
Damage to the CNS can result in paralysis. The loss of both voluntary and involuntary motor control occurs in this type of paralysis
What is flaccid paralysis
In the biceps brachii and patellar tendon stretch reflexes, this structure in the muscle acts as the receptor, detecting stretch
What is a muscle spindle
Short preganglionic and long postganglionic fibers are characteristic of this division
What is the sympathetic division
Goblet cells, sweat glands and sebaceous glands are examples of this type of gland
What is an exocrine gland
DAILY DOUBLE YAYAYAYAY :DDDDD
What is dense irregular connective tissue
This region of the brain fine tunes motor commands and allows for the learning of skilled movements
What is the cerebellum
The ophthalmic, maxillary and mandibular nerves form the 3 branches of this cranial nerve, responsible for control of the muscles of mastication.
What is the trigeminal nerve
The binding of acetylcholine to a nicotinic receptor will always have this effect on subsequent neurons
What is excitation
This type of connective tissue functions to resist multidirectional stress
What is dense irregular connective tissue
Flexion refers to movement away from anatomical position through this plane.
What is the sagittal plane
The descending tract carrying voluntary commands from the motor cortex is sometimes referred to as the pyramidal tract. It is also referred to by this name
What is the corticospinal tract
There are two nerves that carry the sense of taste from the tongue. This nerve carries signals from the anterior 2/3 of the tongue, as well as the muscles such as the frontalis, orbicularis oris and orbicularis oculi
What is the facial nerve
A drug that decreases parasympathetic effects would be described with this term
What is parasympatholytic

What is the apical surface
The carpometacarpal joint allows for flexion and abduction. This joint falls under this category of joint
What is a saddle joint
