Cranial Nerves The human body is a unique and fascinating entity. There is not much notice taken of the features the human body is capable of. The brain is necessary to perform day-to-day actions‚ such as the ability to speak‚ and see amongst us. This brain is made up of simple mater (Pia mater‚ Arachnoid mater‚ Dura mater) and the cranial surface to protect the brain. We live our daily lives without acknowledging the importance of this organ‚ the brain‚ unless you’re a medical student of

Cranial Nerves The brain and spinal cord (CNS) are connected to parts of the body by nerves and cell bodies called the peripheral nervous system. The PNS contains all of the nervous tissue outside the brain and spinal cord. Afferent (sensory) nerve fibers-conduct nerve impulses toward the CNS Efferent (motor) nerve fibers-conduct nerve pulses away Sensory Somatic System – Carries nerve impulses from the senses to the CNS and also carries the impulses to the skeletal muscles and glands

Cranial Nerve Palsy: with an Emphasis on Sixth Cranial Nerve Palsy Cranial Nerve Palsy With an Emphasis on Sixth Cranial Nerve Palsy I. What are Cranial Nerves? * Cranial nerves are nerves that come directly from the brain stem in contrast to spinal nerves which come from segments of the spinal cord. * There are twelve Cranial nerves in humans that fit this description. * They mainly serve the motor and sensory systems of the head and neck region; except for the tenth

A growing number of researchers regard the question of how much heredity and environment contribute to differences among people as Selected Answer: mainly answered by DNA. Question 2 0.5 out of 0.5 points Fetal monitors Selected Answer: track the baby’s heart rate during labor. Question 3 0 out of 0.5 points Patsy and Terry are fraternal twins. This type of twinning results from Selected Answer: the fertilization of one ovum by two Y-bearing sperm

Handout Lab 5 - Cranial Nerves: Assessment of Functions INTRODUCTION The central nervous system (CNS) consists of the brain and the spinal cord. The CNS receives sensory information from other parts of the body or the body’s external environment and transmits motor information to other parts of the body by way of the peripheral nervous system (PNS). The PNS of the human includes 31 pairs of spinal nerves and 12 pairs of cranial nerves. Some nerves contain only motor nerve fibers (efferent
