NURS 3444 Lecture Notes - Lecture 10: Pia Mater, Frontal Lobe, Neural Tube
Document Summary
Ventricle allows to get nutrients into brain. Frontal lobe = give us unique thinking, not like other animals. The skull and brain grow and develop rapidly during early childhood. Infants and young children are at higher risk for injury to the brain and spinal cord because of developing anatomic structures. As sutures ossify/solidify, better protection of brain. No expansion of skull after 5 (picture) dendrites connect as you grow. Cns development - time of rapid growth sensitive fetal periods- closes folic acid* 1st 8 weeks- neural tube develops and (important for pregnant moms to have enough folic acid) Increase layers at birth, only 2 % as an adult as much during 1st year as. All of which can cause increased intracranial pressure. Full consciousness alertness and cognitive power. Unconsciousness depressed cerebral function or the inability of the brain to respond to stimuli. Confusion impaired decision making, disorientation to time and place.
