Do the spinal nerves branch off of the spinal cord?
Yes, some spinal nerves do branch off of the spinal cord, so the nerves can collect the messages for the body.
What is the brachial plexus group?
This group of nerves innervates the muscles and skin of the entire upper limbs except the Trapezius muscle and the skin near the axilla (arm pit). The plexus comes off the spinal cord at C4,C5,C6,C7,C8 and T1 where they mix and form a plexus. There are 5 main nerves that are formed: Musculocutaneous, axillary, radial, median and ulnar nerves.
The bulge in the spinal cord that gives off nerves to the upper limbs is called?
Lumbar enlargement.
Nervouse systeem consists of the brain and spinal cord?
Yes, plus all of the millions of nerves which branch off of the spinal cord.
Spinal nerves branch off the?
Tiny blood vessels that allow substances to pass between the blood and body tissues are called
Why are there 31 pairs of spinal nerve yet you only have 30 vertebrae?
You have 33 vertebrae. (8) Cervical, (12) Thoracic, (5) Lumbar, (5) Sacral, (3) Coccygeal. However, the coccygeal only gives off 1 coccygeal n. 8+12+5+5+1 = 31 spinal nerves

With marked narrowing of the neural foramina?
The Neural Foramen are grooves in the vertebra, just behind the vertebral body that the nerves that branch off the spinal cord exit the spinal canal from. If they are grossly patent they are open, and free from obstruction, so there is no compression of the nerves that course through these channels.
What does the spinal cord do to help the rest of the nervous system?
The spinal cord is like the main road through a city, it provides a pathway down the body for the other nerves to branch off and reach muscles, tissues, organs etc. and for these nerves to join back up and return to the brain.
What is the function of the axillary nerve?
axillary nerve or known as circumflex nerve is a nerve of the human body that comes off the brachial plexus. Brachial plexus is responsible for cutaneous and muscular innervation of the entire upper limb-Drave 10
What does capacious neural foramina mean?
The Neural Formaina are holes that are formed between each joint of the spinal column through which the spinal nerves that branch off the spinal cord pass. These nerves go to your arms, legs, torso and various organs, carrying messages to and from the brain and body. Capacious means open and spacious, indicating that the nerves are not compromised by the degeneration of the spinal joints that can narrow the Neural Formamina.
Which nerves requlate the heartbeat?
There are several nerves that regulate the heartbeat. The heartbeat starts when a signal is given off from the SA node. The main nerves in the heart are called the Purkinje Fibers.
