humerus at shoulder joint
what does the pectoralis minor move as a prime mover?
scapula
what does the pectorals major move as a prime mover?
humerus at shoulder joint
what does the serrates anterior move as a prime mover?

The outermost portion of the brain is known as the cerebral cortex, and would consist of:
ganglia
nerves
axons
gray matter
tracts
gray matter
the cerebral cortex consists mostly of cell bodies, which in the CNS make up gray matter
In a functional classification of neurons, those located within the CNS between sensory and motor neurons would be referred to as what type of neuron?
interneuron
Cells of the nervous system that support and protect neurons are known as what?
glial
the MOTOR nerve root could also be called
the anterior nerve root
the posterior nerve root conveys what type on info
sensory

teres minor
brachialis
triceps brachii
pronator quadratus
teres major

Which portion of the brain is connected to the pituitary gland?
the hypothalamus
SOMATIC MOTOR neurons lead to:
the CNS
skeletal muscles
cardiac muscles
glands
skeletal muscles
Neurons convey impulses across synapses via chemicals known collectively as
neurotransmitters
What is the name of the middle of the three spinal meninges?
arachnoid
what type of matter are myelinated axons in the CNS?
white matter
what convey impulses FROM the cell body
axons
what convey impulses TOWARDS the cell body
dendrites
a cluster of cell bodies in the PNS
ganglion
The spinal cord ends at approximately the level of which vertebrae?
L1/L2
Cerebrospinal fluid (CSF) is found in all of these locations EXCEPT:
The limbic system
The central canal of the spinal cord
The subarachnoid space of the brain
The third ventricle
the limbic system
3 parts of the brain stem
midbrain
pons
medulla oblongata
Which muscle is a prime mover for protraction of the scapula?
teres minor
teres major
rhomboids
serratus anterior
serrates anterior
The part of the brain most closely associated with balance, posture and equilibrium is the:
cerebellum
Which structure primarily functions to convey sensory information?
anterior nerve root
anterior gray horn
descending tracts
posterior nerve root
posterior nerve root
Collectively, sensory neurons would make up which division of the nervous system?
afferent
The portion of the brain most responsible for many homeostatic functions such as thirst, hunger, urine output and temperature is the:
hypothalamus
