関連するムービーとテキストで提供される詳細情報は十分にその場でザリガニのMROの活動を記録するために重要なステップを提供している。私たちの報告書の一つの目標は、感覚生理学の基本概念を教えるための調査研究室を実行する学生で、この準備のための可能性の意識を高めることです。最小限の生理食塩水を浴びている間の準備は実行可能性に非常に堅牢です。 MROの筋肉のモータ制御は、識別が伝送における規制とシナプス可塑性の潜在的なだけでなく、興奮性と抑制性ニューロンの伝送の有効性は、調査のための空地のままされています（Elekesとフローリー、1987A、B、フローリーとフローリー、1955カフラー、1954年、カフラーとEyzaguirre、1955）。 この製剤は、優れた一次調査だけでなく、デモンストレーションではMROの生物学を理解するために動物内での実験条件の数だけでなく、運動の自然な範囲を調査するために使用することができます。 Edwards ら、1981;。Purali、1997; RydqvistとPurali、1991; Rydqvistこれらの感覚ニューロンの生物物理学的特性は、部分的に維持刺激（Brownら、1978と神経活動の適応の彼らの自然の中で解決されていますとSwerup、1991）。しかし、これらの感覚受容器とそれに関連する筋線維（Cooper ら、2003;パーストルとマクミラン、1990）上でわずか数レポートのアドレス神経調節。レポートは、体液中に存在することが知られている多くの化合物のほんの一部を扱う。変調器の多くの変調器とカクテルは、MROの複合体（筋肉や神経細胞）で検査されずに残っている。パーストルとマクミラン（1990）は、様々な甲殻類の種間MROsの活動に神経修飾物質5 - HTとオクトパミンを検討し、種の違いがあることを指摘しました。彼らは詳細にこれらの神経修飾物質の長期的な影響もMROの異なる静的な位置での活動への影響を調べていませんでした。 。ラビンら、2009;。マリノら準備のこのタイプの運動単位のabnormities（パテルら 、2009と人間のためのリハビリテーションと疾患管理において重要である神経処理の知覚と制御の基礎を理解するのに役立ちます。、2010）。アクセス可能な無脊椎動物の調製品で関節の動きを監視するための入力と発火パターンの様々な種類のロボット/プロテーゼ（マクミランとPatullo、2001）で使用することができます。いくつかの方法で有益であることができるこの準備のための答えを待っている多くの疑問が残っています。

muscle receptor organs in the crayfish abdomen: a student laboratory exercise in proprioception

この実験の主な目的は、動物のための固有感覚情報として関節の動きと位置の情報を伝える一次感覚ニューロンを示すことです。この実験の追加の目的は、解剖顕微鏡下で染色、解剖と神経細胞と感覚の構造の観察により、準備の解剖学を学ぶことです。これは、共同体の器官や染色技術から電気的活動を記録するための基本的な神経生理学的機器を使用して実行されます。ザリガニの筋肉の受容体の器官（MRO）のシステムは、電気生理学的記録のためのより容易にアクセス可能な比較モデルとしてのを助ける哺乳類の錘内筋紡錘、に似ています。さらに、これらは準備の間で識別可能な感覚ニューロンである。準備は、学生の実験演習のための従順である時間のための最小限の生理食塩水で実行可能です。 MROは、システムで変更することができますゲインとともに動きと静止位置の動的な信号の調節作用との統合のサイトに興味深い質問を促す神経調節の影響を受けやすくなります。
