What fibers do ventral spinal cord roots contain?
The ventral roots contain motor fibers.
Fibers type in the ventral root?
motor
Are dorsal and ventral roots spinal nerves?
The ventral roots contains motor fibers, responsible for motion, whereas the dorsal sensory fibers, responsible for touch and feeling.
Does the ventral ramus contain only motor fibers?
True
What part of a spinal nerve contains only efferent fibers?
The ventral root of the spinal nerve has the efferent fibers and the dorsal root has the afferent. Prior to joining each other in the spine they each consist of only those fibers.
How are molecules in wood arranged?
molecules are arranged in good order along the fibers
What part of the spinal nerve consists of motor fibers leaving the spinal cord?
The ventral root.
What type of nerve fibers are found in the ventral ramus of a spinal nerve?
Both sensory and motor
Quartz crystals arranged in parallel fibers a gemstone?
chalcedony
How does the collagen structure of hypertrophic scars differ from that of keloids?
The collagen fibers in a hypertrophic scar are shorter and generally arranged in a wavelike pattern, whereas the collagen fibers in keloids tend to be randomly arranged
How are muscle fibers arranged to form a muscle?
Muscle fibers can be arranged into two basic structural patterns, fusiform and pinnate. Most human muscles are fusiform, with the fibers largely arranged parallel along the muscle's longitudinal axis. In many of the larger muscles the fibers are inserted obliquely into the tendon, and this arrangement resembles a feather. The fibers in a pinnate (feather) muscle are shorter than those of a fusiform muscle. The arrangement of pinnate muscle fibers can be single or double, as in muscles of the forearm, or multipinnate, as in the gluteus maximus or deltoid.
Are effernet nerve fibers described as motor nerve fibers?
Yes, remember the mnemonic SAME DAVESAME DAVE:sensory is afferent, motor is efferentdorsal is afferent, ventral is efferent
