Chapter 9 IMPULSE AND MOMENTUM COLLISION PROBLEMS A tennis ball and racket collision: a microscopic view COLLISION: FORCE VS TIME GRAPH A large force exerted during a small interval of time is called an impulsive force. LINEAR MOMENTUM The product of the particle’s mass and velocity is called the linear momentum p = mv As a vector quantity‚ the momentum can be represented in terms of its components: px= mvx py= mvy ALTERNATIVE FORM OF NEWTON’S SECOND LAW F = ma = m(dv/dt) =

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

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 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

The vagus nerve is the tenth of the twelve brain nerves. The vagus nerve contributes to the feelings associated with infections such as appetite‚ fatigue and induction of disease behavior. It extends from the brainstem to the abdomen‚ with branches in the neck‚ thorax and abdomen 68. The vagus nerve is part of the autonomic nervous system‚ has efferent fibers‚ ascending signals from the brain to the peripheral organs‚ as well as afferent sensory fibers‚ and transmits information from the peripheral
