Gross Anatomy Flashcards
The major arterial blood supply to the spinal cord is via what?
Anterior spinal artery
Which of the following joints is located distally to the knee joint?:
- Ankle joint
- Elbow joint
- Hip joint
- Intervertebral joint
- Shoulder joint
Ankle joint
Which type of matter are axons located within?
White matter
Which of the following is a function of the parietal lobe?
- General sensation
- Hearing
- Memory formation
- Vision
- Voluntary motor signals
General sensation
Thw lateral ventricles are located deep within which part of the brain?
Cerebrum
The majority of cranial nerves emerge from where?
Brainstem
What is the name of cranial nerve VII?
Facial
What type of neruons does the optic nerve contain?
Sensory
What nerve supplies parasympathetic innervation for muscles responsible for constriction and dilation of the pupil of the eye?
Occulomotor nerve CNIII
What cranial nerve provides general sensation to the skin of the face?
CNV Trigeminal
What is the term used to describe a collection of cell bodies located in the PNS?
Ganglion
What is the effect of cholinergic drugs on the PNS?
Stimulation of the PNS
The terminal end of the spinal cord is called by the name:
Cornus medullaris
The roots of spinal nerves that innervate the muscles and soft tissues of the upper limbs emanate from the _____ aspect of the spinal cord?
Cervical enlargement of the spinal cord
In a spinal tap technique (lumbar puncture), what vertebral level is safe for the placement of the needles?
L3-L4
because the spinal cord typically ends at the L1-L2 level in adults (and slightly lower in infants, around L2-L3). Below this level, the dural sac contains only the cauda equina, a collection of nerve roots, which are less likely to be injured during the procedure.
Poliomyelitis is a viral disease that affect cell bodies of neurones located in the _______ of the spinal cord
Grey matter in the anterior horn
The reason why a spinal nerve is called a mixed nerve is because:
It comprises of a posterior ‘sensory’ root and anterior ‘motor’ root
