LT LabStation

动物生理

使用LT LabStation,动物学和生理学学生可以研究神经和肌肉生理学中的基本和应用概念。课程是由常见的本科昆虫,Annelid,两栖动物和哺乳动物制剂设计的。

实验室准备

前单位准备

This lesson is designed to be used before the Lab. Questions have been set to allow multiple attempts for formative assessment. However, it is very simple to change the setting so that students may make only one attempt and their answers can be graded.
Independent learning (30 minutes)

Lessons

动物代谢

+

在本实验室中,将学习者使用气体分析仪和PowerLab来介绍间接量热法以记录代谢变量。然后使用这些来确定代谢率和呼吸道交换比(RER),这是对呼吸商(RQ)的良好估计。

Cockroach Sensory Nerve

+

在这个实验室中,学习者从蟑螂腿神经中记录复合动作电位(CAP),以响应各种物理刺激。学习者检查盖幅度幅度和频率,并确定代表不同单个轴突的CAP的不同“类”。

Cockroach Ventral Nerve Cord

+

在这个实验室中,学习者记录了蟑螂或类似昆虫的腹神经绳的细胞外动作电位。使用频率直方图比较并分析了自发活动和不同类型的刺激(包括敲击板凳,拍手,空气泡芙和触摸)。学习者还确定腹神经的神经传导速度。

Earthworm Action Potentials

+

在这个实验室中,学习者从麻醉earth(Lumbricus terrestris)中获得动作电位的细胞外记录。他们检查了唤起动作电位所需的阈值电压,首先是中间纤维,然后在侧纤维中。他们还检查了“全有或无人”的反应,耐火周期和中位神经的传导速度。

Earthworm Smooth Muscle

+

In this lab, learners investigate some of the responses of smooth muscle to neurotransmitters, temperature, and ions. The earthworm (Lumbricus terrestris species) gut provides a robust smooth muscle preparation that can be mounted in an organ bath and attached to a force transducer. This arrangement enables learners to measure contraction rate and force.

青蛙心

+

在本实验室中,学习者从原位青蛙心脏(包括收缩力,心电图(ECG))中测量心脏肌肉的一些基本生理特性。学习者还运用心脏坦率的律法来解释心肌伸展与收缩力之间的关系。

Frog Neuromuscular Junction

+

In this lab, learners explore the relationship between skeletal muscle and motor nerve supply. They use an isolated frog gastrocnemius with an intact sciatic nerve to explore twitch recruitment, muscle fatigue, and the effects of tubocurarine.
