Chapter 11 Quizlet Anatomy

3.The long tube-like structure that carries the neural message to other cells on the neuron is the axon.

Homeostasis is what allows our internal system to maintain at a constant condition. In order to maintain equilibrium the body must communicate using the control system. It is essential that the body monitors its conditions whether that be blood pressure, thirst sensation or body temperature (this is either gained or lost). Negative feedback is most important and comes first, this allows for the body to correct itself and get back to a set point when it is off track. There are three components that link with this feedback. A sensor (receptor) sends signals to the control center that something is unusual, the control center compares the many values of our normal body range and decides

The structure that furnishes the axis for the rotation of the head from side to side is the:

The components of the nervous system that are involved in the physical sensation is the peripheral nervous system, which is divided into two groups they are, sensory and motor divisions. The sensory impulse moves through the body by stimulating a receptor in the skin, and it goes through the sensory neurons and also travels through the afferent fibers, the spinal cord and also into the brain.

P4- Explain the physiology of two named body systems in relation to energy metabolism in the body.

The somatic nervous system controls the contractions of skeletal muscles and is under voluntary control.

There are several body systems, for example the digestive system, the respiratory system and cardiovascular system. I am going to look at the respiratory and cardiovascular systems. They are important because they help people grow, reproduce and maintain life. The body system needs energy for it to function. Our body gets energy from digesting food and using it in the respiration process.

What size fibers make up the preganglionic neurons? The postganglionic neurons? Why is the white ramus white, and the gray ramus gray? What does this mean for speed of conduction?

The Central nervous systems include the brain and spinal cord which transfers voluntary nerve impulse to skeletal muscles, skin, muscles, and glands.

Define equilibrium potential: Equilibrium channels can be calculated using the Nernst Equation and the Goldman-Hodgkin-Katz equation. Equilibrium potentials are membrane potentials when an ion does not diffuse through the membrane. It is also associated with potassium leaving the cell through leak channels.

The CNS contains the brain and spinal cord. Its main functions include: processing, integrating, and coordinating sensory information and motor instructions. The sensory data conducts information that is being processed from internal and external conditions the body is experiencing. Motor commands regulate and control peripheral organs (skeletal muscles). The brain functions under memory, emotions, learning, and intelligence. The PNS consist of the neural tissue found outside of the CNS. It functions in sending data to the CNS which motor commands are than carried out to the peripheral tissues/systems. Multiple nerve fibers send sensory data and motor commands in the PNS. The nerves that assist with transmitting data include the cranial nerves and spinal nerve. However, the PNS can be divided into afferent (to bring in) and efferent (to bring out) divisions of transferring data. The afferent division functions in bringing in sensory data to the CNS. Sensory structures are receptors that detect internal/external environmental change and adjusting accordingly. The efferent division functions in carrying out motor commands from the CNS to glands, muscles, and adipose tissue. The efferent division contains somatic

The peripheral nervous system (PNS) is connected directly to the central nervous system, and consists of neurons and nerves that send information back and forth the CNS. Furthermore, the peripheral nervous system can be divided into two sections, the sensory nervous system and the motor nervous system. The Sensory The sensory nervous system is in charge of transmitting data from a variety of internal organs or from external stimuli to the central nervous system using sensory nervous cells. On the other hand, the cells of the motor nervous system (motor neurons), take the impulse from the CNS to effectors, which include glands and muscles. In addition, the motor nervous system can be further divided into the somatic nervous system, controls voluntary actions of the skeletal muscle and external sensory organs, whilst the autonomic nervous system operates

Most neurons do not make direct connections with surrounding neurons, signals (molecules) must make the transition from the presynaptic (upstream) neuron to the postsynaptic (downstream) neuron. This transition space is called the synaptic cleft. The exchange of information from the pre- to postsynaptic neuron is called a synapse.

My hand was sprinting across the page with charcoal in palm, and the finish line of my sketch was in sight. The image of a model’s face was quickly appearing, and the proportions of her eyes-to-nose and ear-to-mouth were just right. Proportions of the human face were something I learned in art class, whereas the details in her eyes were something I learned in anatomy class.
