Q1: Summarise the main development of a child age 0-2‚ 2-5 & 5-8 yrs. 0-2 Years As a child grows the changes in weight and height size are measured on a centile chart‚ these charts show the expected pattern at the particular ages. Development refers to the skills and abilities that you learn through life‚ but as we all know children are all individual and so when centile charts are used they are based on the “average” child but all children meet these different goals in their own time and don’t

Site Plan | I. Neurons/nerve cells A neuron is a cell specialized to conduct electrochemical impulses called nerve impulses or action potentials. Neuron is the main cellular component of the nervous system‚ a specialized type of cell that integrates electrochemical activity of the other neurons that are connected to it and that propagates that integrated activity to other neurons. They are the basic information processing structures in the CNS.

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 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
